Is there a way to add points to a group that stray too far away from it's original point position?

What do you mean by original P?
Is this for particle sim?

You can do something like this assuming you stored the original P in v@Porig attribute

Well it is for a rigids sim but sure! I have a wall getting destroyed. I pretty much want to have the pieces that have fallen to the ground to be in it's own group and my thought was if it strayed from it's original point position based on a threshold that would be a good enough mask for that.

I originally tried doing inactive v.s. active and that wasn't favorable results. There might be a better way than what I was asking for from you but that seamed logical enough to try.
