For every site that we've been able to successfully reverse a penalty, the time period was roughly 6 months; my guess on this is that there is some sort of cycle for penalized sites, similar to what MattC described with the way G penalizes.

If you think you fixed the problem, try to forget about it and move on to something else, checking back every month or so.
