Erika, when I began, my BPI was at about 20th %ile, with speed being, and still being my lowest. Now it is in the 30's, but that is 3X what it was when I started. My overall BPI is much better as well. I was very shocked to see how low I was after the initial trial and that's what motivated me to work on things.
Kitty, don't hate us when you try Penguin Pursuit for the first time!
