How much doe the stones more around as you go over them?

I've ridden my WTB Mutano Raptors (55/55 size) on what I call
"railroad ballast" a good bit with decent results.

My sense is the bigger the tire and the lower the pressure, the
better.

215# rider, tires at 35-40 psi.

But the stuff I ride on pretty much stays put as I'm going over
it. * If the stones shifted around too much it might be a
different story.

The stone moves quite a bit. Looking back it looks more like someone
was dragging a spade shovel or riding a dirt bike than it does like
someone was riding a bicycle through. I'm ~200 lbs myself. My next
attempt, unless someone convinces me otherwise, will be at 35lbs
pressure. I know I have not ridden gravel with pressure that low, so
it'll be interesting to compare against. I'll post back with results
once I get a chance to try it, which may be a few days with this
weather.
