Dr. Joe 'fesses up...
Don't feel so bad. I didn't even do the calculations...

...when I am actually designing a robot, I do the calculations (though I sometimes still get it wrong -- ask me why our robot had a 6 tooth sprocket last year ;-), but for this thread I just relied on my experience with 2 motors per side in 1999, 2001, & 2002. I was confident that it could be done and just signed on the bottom line -- skipping the fine print.

I should have suspected something was wrong when John's calcs showed the system to be so marginal (which was not my experience), but I was blinded by the circuit breaker concern and I just missed it.

Thanks to Matt for checking the calcutions (by the way, everyone should take the time right now to give positive reps to both John and Matt for the work they have put into this entire thread -- yes do it right now -- it only take a few seconds).
