you are spot on with the schedule, but I haven't seen the following:

If next week your total site serp referrals goes up (from 'minor updates' that is, or between 'sub-major updates' not from tonights 'major update'), that will likely continue for the next three weeks. If they go down, they will continue downward until the next 3 weeks until the next 'major update'.
