ACC is a relative error, so ACC = 0.001 gives three digits. Leaving ACC unset, or set to something <= 0 gives maximum precision, which can take a long time.

I used ACC=.001 for my test runs.

I always set ACC out of habit, but I assume your note means that ACC is reset (or unset) each time you enter the Integral function (as opposed to re-using the value last used)?

No, INTEG doesn't change or unset ACC. I was referring to the case in which the ACC variable doesn't exist (hasn't been created, or has been CLV-ed); in that case, INTEG behaves as with ACC=0.
