Not too surprisingly, the final rankings of my repeat experiment were the same as before. There was probably no difference whether I left the pre-soaked stains in water (without scrubbing) or rinsed them off with running tap water and gentle scrubbing, because when I did the latter, I took great pains to ensure that time for rinsing and technique of scrubbing was as identical as possible. :) However, having said that, that would have contributed to that variable (rinsing off) not being constant, which was why I took the trouble to repeat the experiment.
Well, that's all for the time being, and I'm almost done with the entire SIP! Wheeeee!!!! :D
