My experience is that AIVS went too far. Its rinsability is clearly inferior to RRL's. It left audible residue that took multiple rinse/vac cycles to remove.
When using my VPI, I found that if I have a strong light shining on the record, and I watch the run out area, I can see when all the flud is picked up. It's usually more than the 2 revolutions that VPI suggests.
If you're using a Loricraft I can see how you might have a problem since you only get one pass per cycle.
