I posted this elsewhere, before DAPI showed me his own excellent work on the topic. My plot is fairly redundant, though nicely corroborates DAPI's 2012 trace.
I would just add the comment that there are effectively three phases:
(1) During the first month after submission opens (June 5th to early July), verification time increases rapidly with each passing day.
(2) During the second month (early July to early August), verification time is steady at about 5-6 weeks.
(3) Verification time decreases gradually beginning in early August.

I have attempted to summarize submission data (using the AMCAS twitter postings for apps received) and verification data (using this thread information) in a single graphic. It may be useful for future applicants.
The black trace shows the cumulative number of apps submitted, which increases somewhat linearly over the course of the application season before tapering off slightly late in the admissions season (not shown).
More interesting is the red trace, which approximates the
maximum verification time for primary app submissions on a given date (assumes transcripts have been received by AAMC before that date). Maximum AMCAS verification time increases rapidly from about
one week for June 5th submissions to
four weeks for June 25th submissions. From late June through mid August, the verification time is about 5 to 6 weeks, before declining for late submissions.
