I agree with some of what you say, but disagree with most of it.
Power is what moves a vehicle not volts or Amps! Power is a combination of volts x amps. If your vehicle takes 1000 Watts (arbitrary number) at peak power, it will take about 1000 watts at peak power regardless of using 4S, 5S or 10S.
You get efficiency with a HV setup because it will take much less amps at 10S than it will at 4S to produce the same power.
The power ratings you are providing C rating x pack Ah x voltage are the continous watts the pack can theoretically put out, not the actual W/hr ratings of the pack. If you drive a 30C pack at 30C full time it will last for 2 minutes.
You say that our motors can hit 100 Amps regularly and they do, yes that is true. But that is what the peak 50C or 60C rating of the pack is for - an instantaneous burst of energy and nothing more. But as you go up in voltage that peak Amp draw is much less - and that is the whole point of HV.
Since heat is not an issue in this thread as you describe I won't waste my time elaborating.
If your arguement is to go from a 4S to a 5S pack and stay with 5000mAh cells and get better runtime due to efficiency then yes - you may get a few more minutes, but at the same time you'll need more power for the same performance so it's not a true performance gain.
