If I were you, I'd cut my chin pump in half, then watch closely for a week or two (bear in mind that there may be a time delay effect). Watch particularly your involvement in social interactions...that's the real key. If all's well (and I have a feeling it will be), add a little bit more duration every couple of days. If not, take off some duration. Meanwhile, of course, I wouldn't even think of adding on any new practices!
Woops...I just reread your posting. I'd strongly suggest you do your self pacing by reducing the daily time of a given practice, rather than stopping it entirely on a given day. AYP is a daily practice, and needs the constant daily repetition to be effective, so it's not really the AYP way to skip days. So, again, I'd suggest you cut the time of chin pump down, not the daily frequency.
