I also want to re-emphasize something that Joe mentioned: the definition of "competitive advantage" really depends upon the game.
I agree that in your typical game, the numbers you present above (especially the 150 lb pushing force number) would be about your pushing limit. However, in the 2002 game, we determined that our robot would need to push with a force of about 720 - 960 lbs before our treads would start to slip. For this game, having 150 lb. of pushing force would not be an advantage at all.
The point is: assuming a peak pushing force number before the game is announced can get you in trouble... unless you have a shifter. Then you can just pop in a new ultra-low ratio. However, your strategy may be such that a shifter is irrelevant.
