What is an acceptable tolerance of flatness for tablesaw tables?

I purchased a new Unisaw (but the old model) last fall. Because of busyness of life including a new baby, I am just now assembling the extension table to the saw. I am having a heck of a time lining up the edge of the extension to the saw table. I then measured with a straight edge and feelers and found the tablesaw table from the infeed side to the outfeed side and the outfeed is 0.015 out of flat and lower than the infeed. So I am having trouble lining up the entension table without a bump on the rear.

I could probably shim the extension table to be out of flat to match the tablesaw, but I am not sure I like that solution. Before I call up Delta, I was wondering what level of flatness is acceptable?

I’m not sure what you are saying. Is it that the table top is thinner at the back end by .015 or that it is lower?
If it is thinner then get in touch with Delta. If it is lower then just shim up the back with a wedge or spacer.

It is my belief that shimming the extensions is standard operating procedure.
