was lazy and turning some spindles and sanded at spindle turning speed
and did not see much difference


High speed sanding can generate heat with causes the sand-paper to
break down.

I've also seen the heat cause checks (cracks) in the wood. Slower is
better.

I usually power sand, since I can free-wheel the lathe I just leave it
"off" and let the sander spin the object

I like to power sand with the 2" disk in my drill. Doing so, and
varying the speed helps create a random pattern, sort of like a random
orbit sander. So moderate lathe speed, and moderate sander speed is
what I usually shoot for...
