Hello fdr214 (what's in a name... ;-)),
Under normal circumstances 6 minutes should be enough. But since you never know: if I were you, I would book the next train. Perhaps not necessary, but just to make sure. According to my information you cannot use reservations for a next train if you miss the one you have reservations for.
So here's an answer that gives you not much of a solution. I think it's really up to you, do you want to take the very small risk or rather not. I'm sorry that I can't be more specific.
