After writing a front-end to Ether's sims and playing with it a bit, very large swings in weight will have an effect on acceleration from a theory perspective. Torque remains the same, but the mass is larger, thus acceleration is lower. For the same amount of time, it nets a shorter distance traveled. Small changes (5lbs here, 5lbs there) seem to have no discernible difference in acceleration on a FRC field since it's less than an inch or two of difference.
Preview
here. Requires Java 8, Win7/CentOS 6+/Who knows what for a Mac. Probably works in Ubuntu 12.04+, but I can't tell what version of GTK it ships with at the moment. The preview is just the latest iteration of layout ideas I'm playing with. For example, I don't think it'll have a web viewer upon release, which is what the current preview has.
