Well the 5SFE isn't a 3VZ or 1MZ with double torque peaks (and a flat torque curve altogether). On the 5SFE, if you drop out of the peak torque range on upshift, you do lose time, but you also lose a little time revving the motor past its power peak, but only in higher gears. If you only rev to 5250, you'll likely drop to 3500rpm in the lower gears, which is way off the mark in terms of the torque peak. If this were a 3VZ/1MZ, 3500 is where one of the 2 torque peaks are, so it probably wouldn't hurt as much.
So, in 1st and 2nd gears, you'll need to push the motor to over 6000rpm, but because of how strong the gearing is, it won't matter that the motor doesn't produce any reasonable power after its peak because it revs pretty quickly.
1st gear @ 5250 drops you to 3250 on upshift to 2nd
2nd gear @ 5250 drops you to 3500 on upshift to 3rd
3rd and 4th gear drop to 4100rpm and 4200rpm (respectively) from 5250rpm, which is pretty reasonable.
