Hi @carramone ,
Yes, you can do that, but the Factor of the Length of the Curve Circle goes from 0 to 1, Adding a Value, can potentially result in a Value higher than 1 (and that would probably be read as a Factor of 1), so to be sure, you might want to use a Math > Modulo 1, just before plugging it into the Factor of the Sample Curve Node. That way, if you get to a Value of 1.01, for instance, that would be turned into 0.01.
