I have a very small sample, as I am a poor record keeper and only recently started to keep good track of my SNGs. Also, due to work and family, I only play at most a couple of SNGs per night.

With that explanation, I have good records for my last 100 SNGs exactly. My ROI in that last 100 is 44.3%, my win percentage is 14.9% and my in the money percentage is 45.7%. While I don't have data for anything before, these numbers don't appear to be much different from whatever I was doing before I started paying better attention, but I can't support that with anything other than my account records.
