Hah, depress yourself with the optimum shift point calculator at
http://www.prestage.com/
Inputing the ratios for a T-5 (2.95, 1.94, 1.34, 1.00, .65) and simulated engine power curve, The 1st to 2nd shift only resulted in a loss of 170 ft/lbs @ 7000 rpm.
extending the power to 12000 rpm showed a gain if I shifted at 8000 rpm in later shifts! (like a hydraulic roller motor could rev that high! and produce). Helpful none the less
