Actually Sportz, I'd like to email you if possible, I think I've come up with something that looks o.k. at this point using the Unitab ratings as a base rating only.
Applying my own points additions and deductions, I have come up with some that rate 101.
There have been 10 of them over the last two Saturday's returning 21 units.
Now admittedly this is early days, but if anyone has a spreadsheet of past meetings with the unitab ratings, then I'd know a bit better.
Anyhow, if you're interested drop me a line:

Also when it's finalised, I owe Kenny Victor a good system, haven't forgotten you mate
