Default "Block Learn" vs. "Intergrator Value"?

I've much more experience with scanning the LT1 (my previous toy), so recent Qs re LT5 O2s got me curious about something, i.e., "block learn" and "intergrator" values for the LT5...

A really useful tool for observing the ECM's reaction to O2 signals is the injector dwell time milliseconds. Dwell time is a direct measurement of the ECM's reaction to O2 signals (available on the (95) LT1 ECMs). But, apparently, the LT5's ECM doesn't have that data available; or at least not on my AutoXray scanner. So, check me out here:

I'm left with-
-the O2 millivolt value averages over 1 sec. time
-left and right block learn values
-left and right O2 cross counts
-left and right intergrator values.

I feel pretty clear on the O2 voltage readings and cross counts interpritations, but I'm a little fuzzy on "block learn" and "intergrator" - just how and what, exactly, are the derivitives of these values?

My understanding is the block learn values are indicative of fuel flow values and intergrator values are indicative of air/fuel mix. Is this the correct way to read these values? (How I miss "injector dwell"!!).
