Building bench on un-even surface

I am gearing up to build a work bench that will sit on an old, uneven concrete floor that slopes to a drain. What is the best way to ensure the bench top is level on the uneven surface; need to determine the proper length of each leg. I have ideas, but I just wanted to hear from the carpentry experts before forging ahead.

I'd lean toward leveling feet.

One example:

I would build it with same length legs, then start where the highest one will set with straightedge and 4' level to see how much shim I needed under the remaining legs. This way you don't have to cut the legs again if you decide to relocate it. If it's going to be a built-in, with a ledger lagged to the wall, then yes, I would use a level to mark the front legs and cut them to fit.

If you don't want to use shims, cut the legs to level as follows. Take the height of the maximum gap and subtract the height of the gap on the leg to be cut. ALL HEIGHTS ARE MEASURED FROM THE BOTTOM OF THE LEG.This is the height to cut from the leg. For example, with the table level, one leg is against the floor ( 0 gap) . The other 3 legs have a gap of 1, 2 and 3 respectively with 3 being the maximum gap..
For the leg with 0 gap, you cut off 3 minus 0 equals 3. You cut 3 minus 1 equals 2 from the leg with the 1 gap. You cut 3 minus 2 equals 1 from the leg with the 2 gap. You cut nothing from the leg with the 3 gap since 3 minus 3 equals 0. Hope this helps.

You've gotten good information but I'd like to simplify it. Place initial boards on the wall and level them, then build everything around them, keeping all your work level as you continue. If you'd like, add level furring strips to the wall as needed.
