Hi Michael,

It could be the number of points based on percentage where 100% would be the actual number of points, and 0% the lowest possible.

Or maybe it could work with tolerance values as well, proportional to the scale of the objects.

Like your example it could range from

0.01 and 0.5 on a curve having a length of 10
0.1 and 5 on a curve having a length of 100 and so on.
