Oh, A1c's!  Mine was 9.4 before I went on the pump (boo-hiss on NPH and R), immediately came down to 7.2 within 3 months of going on the pump, got it under 7.0 for the next several years (6.7-6.9), and am now running between 6.0 and 6.2 (as of today, 6.2!).  Yes, a lot of it is diligence, as I'm testing more often, but a lot of it is accurate dosing and accurate corrections, which, to me at least, are easier on the pump.  But then, I can't do math in my head anymore, lol.
