To be frank, there is no 1 standard way of stringing. Different strokes for different folks. As long as the quality of stringing is good. Some are jealous already trying to be little people. I understand your ego mate. lol
I agree there is no "REAL" Standard way, but for warranty references Yonex does require to have 4 knots otherwise it technically voids their warranty, so from a manufactuers stand point they have a standard way to string their rackets. I doubt many people in this thread are jealous, most people here are good stringers wanting to hone their craft and become better stringers, as for an ego, if you watch my videos, you are welcome to comment and critic my way of stringing. If anyone has an ego that doesn't want to be hurt, I noticed you disabled comments on your videos, so no one can critic your stringing. You can make any comments you want about my stringing, I have seen some terrible videos, but there is one thing I might see that makes sense, so in hindsight it is not really terrible.
An analogy is you drive a car from A to B. There are different cars, using different petrols, different drivers, different routes. Car manufacturer (stringing machines) have their recommendations (biased or trying to create a niche). Left or righthand drive. So many variables and approaches. Up to you if you want to follow the recommendations.
If you follow their recommendations what is so bad?
In a tournament, there are about 500 rackets to string, u got time for 4 knots? Wake up dude.
Have you ever strung at a tournament? and Yes at tournaments that I have strung at, I use 4 knots, so I am awake usually until maybe the last 2 days then I get a bit sleepy. Lets say we are stringing 25 rackets a day on average between 3 or 4 stringers, Tuesday-Friday about 100 rackets and semi finals and finals maybe another 20-25 rackets those 2 days, so Yes we can string as a team about 500 rackets in a tournament with 4 knots.
Fyi, old days in early 80s ZJH days, some pro players prefer less strings at the bottom end. For better repulsion. I am a pro player (ex).
If you are a pro player back in the day, I am sure people can respect that, to be honest if you had good credientals you wouldn't have to tell people you were/are a pro player, everyone can respect TBH is a pro player, he doesn't have to tell people or your ZJH, people respect that these people are pro players, if you need to boost your ego then you remind people you are a pro player. You don't have to remind people who know you, that you are a pro player, if you arethen people give you the respect you deserve.
Until you hit 20 years of stringing at least or play at pro level, then come talk to me. I can use a lousy but reasonably strung racket to still beat u in a game. lol
I don't doubt you can beat me, I am not a badminton player, I am a badminton stringer. I don't have to say I am a Pro badminton stringer, because I have built a reputation as being a reputable stringer. What dose having 20 years of stringing experience have to do with anything? If you wanted to teach people how to string you wouldn't have such an ego saying come talk to me. If someone has 1 year stringing experience I would still take the time to listen to them and hear what they say. They have some good advise for me, I will listen, for you to say until you hit 20 years of stringing then come talk to me. Pretty big ego to me. By the way I have been stringing for over 26 years, started stringing in 1996 at a badminton shop in San Jose, CA USA called Asby Sports. Andy Gouw and 1992 USA Olympian Ben Lee taught me how to string. Of course they are no master stringers but average people who wanted to teach their craft to me. And again I progressed my stringing skills way beyond theirs. Again they were no master stringers but average stringers who loved the sport and taught me the craft of stringing. No ego's here.
Some just hates the reality and call others troll.

Sad case. This guy is GWS bro, he is no longer a pro? He is a Olympic silver medalist for god sake. TBH is AE champ. Give some respects. Be kind and change your mentality.
This I don't understand where you are coming from, I would say most players want their rackets strung by professional stringing teams, if you want to give some respect then how about players like Tony Gunawan Olympic GOLD medalist 2 time World Champion, 2 time All England Champion or Halim Harayanto Ho World Champion, All England Champion, if they string their rackets they do 4 knots, or if I string them I do 4 knots, since at least 2005, the Yonex Stringing team has been doing 4 knots unless requested to or due to unforseen circumstances. Most players nowadays are used to 4 knots.
You have a more expensive machine doesnt mean you are right. There is always a better machine and so called arrogant stringer in future. All are just feeding their ego to protect or justify their existence to string 4 knots.
In my case it usually does mean I am right, BUT, I always listen to other people's opinions. I think there are arrogant stringers out there, I have a friend who thinks Yonex is the best and ALWAYS pushes his opinion on everyone. I can listen to everyone who thinks their machine is better and I can respect their opinion. If you don't think the Yonex Protech 8 is your cup of tea, I can respect that, if you want to string on a 2 point mounting system machine with a rotational pull that you wrap around like 5 times, I can respect the machine you use. In no way shape or form am I justifying 4 knots, I have friends who like 2 knots, I am not saying they are stupid like some people say stupid people use 4 knots. My customers are happy with my stringing as I believe your customers are happy with your stringing. If back in the day I am stringing 3000+ rackets a year in my shop and most people don't complain, it can't be all that bad?
Use your experience to manage the tension needed as long as they are consistent.
The guide now is 24lbs for beginners, 26lbs for intermediates and 28 for advance players. For pros, their hand is much stronger, 30lbs above. Go suck it up. How much diff can they be?
What is needed to be sucked up?I guess where you are maybe because of humidity or temperature factors different countries have different recommendations. In the US I might recommend 20-23 for a beginner, 23-26 for an intermedate and 26+ for advanced, in Japan I have seen string tensions down to 14 pounds, but most older ladies might string at 18 pounds, so Temperature can affect stringing, it does in tennis too, if a pro is playing at night they might string tighter because conditions are cold, affternoon they might string a little looser because it is hotter.
In 80s, you minus 2lbs above, because of the quality of the materials used for the strings or rackets.Time changed. Even fake rackets can take in 30lbs easily now.
I was doing 10% (+2 pounds on my crosses) sometimes because players in the 90's still wanted that feel to oval their rackets and avoid them from rounding out on a 2 point mounting system for their aluminum frames.
In a 2 knots string snapped situation, if it breaks at the 4 corners or junctions, its safer. Vertical and horizontal can escape frame cracks. 4 knots cant. Only applies to high tension rackets.

. Lower tension rackets wont breaks unless stringing is uneven.
Do you see many rackets breaking? Most rackets I see break are from collision, I agree rackets can break when the string breaks, but I rarely see with low tension rackets, I don't think it matters 2 knots or 4 knots at high tensions, if the frame is going to break it is going to break. Yes if your string breaks on main #8, 9 10 or 11 you are going to have uneven pressure on the frame, do you think if you break your string on the side, pressure can be aleviated because you have 2 knots? Where is your logic? Your string is still tight on the other side making the frame uneven, How can 2 knots escape cracks better than 4 knots? If you cut the string on the side of the racket, how many mains lose tension, move? Maybe 5? You still have uneven pressure on the frame. Does my logic make sense? If not prove me wrong, I encourage to hear how you believe 2 knots are better than 4 knots in this situation? I think it is the same. I would like to hear other peoples opinion too. See no ego, asking to learn from others, even you.
Speed of stringing is minor. 15 to 20 mins average.
I agree it is minor, except when you have to string maybe 20+ rackets a day, then it comes in handy. I do not like to use the word speed in my stringing vocabulary but I would say my efficiency in stringing. I am not fast, I am efficient. You might be fast, I am not.
@Cheung @kwun shd pin this up to resolve the mysteries once and for all. Since the pros already said so and you still want to listen to a non pro saying 4 knots is better? Camon. lol
Who is a non pro saying 4 knots is better?
