Question Noticed something VERY intesting today

I was looking at my old dyno sheets from same and different days. I noticed that on my full bolton runs my peak flywheel hp (rpm) was different from my peak rwhp (rpm).

Peak flywheel rpm was 6000 and peak rwhp rpm was ~5700rpms. Anybody ever see this on their cars?

I was wondering why I ran faster if I shifted before a little before 6000 instead of right on it, and I think I see why by looking at my sheets.

I do NOT understand why when the engine is making the most power the wheels start losing a little pull... Does not make sense to me.

btw on a dynodynamics my flywheel peak hp is 426.9 @ 6000rpm
rwhp on same dyno is 333.6 @ 5700rpm.
