A math challenge

True enough.

My scenario only works for a planar surface tipped at any angle. The three legged chair can always be turned so two are horizontal to each other and the adjustable compensate for the slope.

1", 2" and 3" above the lowest one. You can't fit two of the legs on the same block, so the two fixed legs will not be the same height--tilted table.

I have the answer, not the one the OP wanted but an answer none the less.

Build a tripod with a center pipe mounted on a ball joint to fit the table top to, the lower end of the pipe will have a 2 cubic foot container filled with mercury(close as possible to floor) weighing about

1700 pounds, table will be stable on any footing and top will be level
