If you're haulin the mail it may not effect your CM nearly as much as if you puttering along a cattrack, right? The faster you're going the more inertia you have and your CM will want to continue on its current path - will you be out of balance? On the other extreme, if you're standing still (without any forward inertia) you'll fall over - that's probably considered being out of balance (until you hit the ground!) Seems like it's kinda speed dependant to me. If I'm going slow, then I either have to 'move up' and balance on the uphill ski or redirect (pivot) my skis to come in line to support the new direction of my CM; If I'm going fast enough, then my CM doesn't really change direction as dramatically and the uphill ski quickly starts to cut across the path it is on, then pushes it where you've now decided it needs to go. Your thoughts?
Anyway, I'm not sure my description is very good, here. I'm thinking about the difference between a sine wave (constant change in one direction, slow to a reverse, then back in the other direction--always changing slightly) and a wave with discontinuities (in this case where the additional force is added to move CoM more dramatically). I'm sure someone else will describe it much better--and I'll learn a better way to say it!
