Drive Train design roadblocks

I've been working for quite a while to finalize plans for a gearbox for this year's bot. I've done much research, and gone through many calculations, but now I seem to be stuck on one factor on the JVN calc sheets. It seems that no matter how much I search for the solution I can't seem to find what "Fractional Weight on A/B Driven Wheels" means. That and the Drivetrain Efficiency (for which I've been assuming 0.65 will work, though I may be wrong) seem to be the only things keeping me from designing a transmission that won't draw too much current.

I was hoping someone could explain these factors to me. I'd really like to get these plans done soon! If I've missed a previous thread applying to this in my search, please tell me.
