I mean, you ideally use every point, but there are cases where you have a few over. I haven't been in DVC long enough to speak to it, I tend to combine 2 to 3 years, so it hasn't been an issue. When I first bought my resale, it had a bunch of points about to expire and I put it into RCI (timeshare program since replaced by another) that DVC partners with and I used them there, but I don't think 4 to 10 points would get you anything in that either. Also, I think DVC lets you buy a few points if short, also sometimes people try to buy left over points from other members, as you are able to transfer points(I believe there are restricts, like you can only do it to one member, and once a year, not cut up all your points and dole them out to 3 members), so folks might buy them off you.
