4K vs. 2Y, not much difference?



No, no, no!!
You should shift after the power peak, not the torque peak.
You can plot torque at the wheels through the gears or power at the wheels through the gears and they will give you the same results as far as shift points. Where the torque available at the wheels in one gear drops below the torque in the next gear will be the shift point although you'd probably want to shift a couple hundred revs higher to accommodate the slight drop in speed during shifting.
It's worth noting that the shift RPM will vary depending on the gear spacing. Typically you want to shift at higher RPM in the lower gears.
Grant did a study of this a year or so ago.
If I had time at work I'd take the time to demonstrate. It'll have to wait till later.
