Was wondering does the computer take a few passes to adjust itself fully to a change in the tune if made at track?

Asking as I made a pass yesterday and it was slower than expected. Looked at datalog and added fuel from 4-7k. Car responded by picking up nearly a tenth. Added a little more fuel to 4-7k and it picked up a lttle more and I left it alone for rest of day. Problem it seemed is it kept picking up each pass to point I gained solid .15 Ended up running pretty damn quick for a hot humid day.

I had added new front O2 sensors with new set of NTK's as my less than year old Bosch's crapped out and were stuck lean.
