I've been googling this for days and I'm just getting confused, I think a fresh set of eyes will have the answer.
I just bought a stock 1995 4x4 GMC Yukon with 5.7 TBI/4L60E, BJYL-$0D-5.7-auto.bin.
I've been logging it cruising at 60MPH on the motorway and the BLM's are all around the 120-121 mark and my INT values are in the 127-131 range.

If my long term BLM's at 120 are on the rich side of things why is the short term integrator sitting right around 128?
It doesn't look like the integrator is trying to pull the BLM's up towards 128, what am I missing here?
