Making The Right Neu Motor Choice?

I am going 5s on my 1515 1y. That puts me right at 40700 rpm which is right about where Neu's are supposed to be most efficent.

I'm just curious where 40k comes from as a good efficiency number? I always remembered reading here that most people shot for the 30-35k range for BL motors.
