Simple question: In CAV, what's the difference between "On Access" and "Stateful"?  Is "Stateful" JUST AS GOOD but faster, or is "On Access" somehow functionally superior?  Is the ONLY difference speed?  If so, why would anyone use "On Access", wouldn't everyone use "Stateful"?

"On Access" is above "Stateful" on the "slider bar" of modes, does this indicate that it's somehow better than "Stateful"?

I don't know which to use.
