How much lean b4 you shim up the stand?

Thanks for the feedback folks.

I shimmed up the full length of the stand with 1/8" backerboard and then did some micro adjustments using playing cards. (It's not like I am any good at poker anyway).

I've got it to within 3/32 of an inch.

I decided that I am going to run a water line for my RO/DI unit to the same area, so while I have the basement ceiling opened up, I'll get my contractor to beef up the joists. He checked them prior to the project and assured me it would be OK. What the heck, it's more work for him and I am sure he won't mind.
