I believe you were right on the money with the first two statements; and yes having a dyno sheet that defines an individuals tq and hp curve does help. I'm not quite sure what you are talking about with the lower gears and the 80% statement???
You should shift when your hp peaks, any time after would be waisting time because your motor is back on the down swing of power, and anytime too soon will short change your motor's peak hp. The only exception, and maybe this is your 20%, is when tractions does not allow for you to reach your peak hp or your peak hp if beyond the capabilities of your motor. Your red line is basically what you shouldn't spin your motor past; it has nothing to do with tq or hp peak.
Sounds to me like some people should hit the books!
Keep your cents, you'll need them to help with your education!
