I came up with that count a long time ago, and haven't done anything with it lately. You can get a very high playing efficiency with it even without true count conversion. A secondary count of 3,5 +1 Ace -2 gives you BRH-2 for betting. You could also use the same secondary count added to AOII to get Halves for betting.

Not right now, but I have started working on my simulator again and I might finally come out with some books or software. I do have simulations showing AOII + Halves has better betting efficiency than Ace-Adjusted AOII.
