Here's the
link for the rating system that
you posted. I don't know if it will stand the test of time like Bisonbison's but it does focus on post flop play which may help OP here. The real reason I sent it though is that it has links to Bisonbison's ratings, and Harv72b's ratings as well as yours. None of these ratings is perfect but when I'm running bad I plug in all 3 ratings (plus the PT defaults) and see where I am. I think looking at your stats four different ways may help give some perspective on where you are and compensate for the relatively small sample size.
