There is the possibility that this "someone" miscalculated and Misbun is just blindly using the data, right? Anyway it just a minor issue. I am just saying it's no big deal if Misbun miscalculated.
I didn't say Misbun is already a great coach. It depends on the performance of LCW in the following few weeks.
LCW is not strong enough to pick a "lower position", many players besides LD and TH can have real threat to him (In contrast, for example, for LD the only real threats are TH and LCW. But for LD, lose in QF or lose in SF do not make much difference, his only goal is the champion). So No. 2, or if possible, No. 1 is still his best choice. And Misbun is just comparing LD and TH from his own perspective, I don't see anything wrong.

It is even okay if Misbun cannot calculate. As you suggested, there must be someone else in the team to do that. But it is Misbun's fault that he made his miscalculation public. Since he cannot calculate (which is okay), he should ask other people first to calculate first.
But because of his limitation, he is a less successful coach. Please realize that Misbun is not the greatest coach yet. You sound like because he cannot calculate so he's the greatest coach. That's against logic.
One reason stops him from the greatest coach is probably that he cannot calculate. Let's back to this WC, he said it's Taufik, not Lindan, the most dangerous opponent. Then why he's happy that Lee CW got the 2nd seed. Since LCW got the 2nd seed, he could meet the most dangerous Taufik in QF. So if Misbun were smart, he would arrange Lee CW's ranking in the 5-8. That way, Lee CW would definitely not meet Taufik before SF. That's the simple power of the calculation.
