Yes, but that number will only be valid in the range of clicks that you used. It should be valid for all the clicks in the scope, but you can't be certain it is, unless you check them all.
The point about the scope possibly not being precisely uniform throughout its entire range of adjustment is a valid one. Particularly when you look at the extreme ends of the range and older scopes that weren't made to be target scopes, so it was rare for people to use that part of the adjustments.
