Re: [ATM] What would you do??

It depends. If the numbers are accurate, the surface is reasonably smooth 
and you're going to by doing mostly deep sky observing then you might want 
to stop right there. On the other hand, if you're mostly interested in lunar 
and planetary work then it wouldn't hurt to push things a little further. 
The big question is, do you have a good handle on exactly what it is you 
need to do to tweak the surface closer to 100% correction? Did you get to 
your present point is a steady controllable fashion or was it more by 
accident? Answer that question and you'll have the answer for the rest.
