Certainly have Mo.

I use the Tas Tab ratings in conjunction with the Unitab ratings to formulate my own set of ratings on the best races. This was the method I used to win the Ratings Challenge we held on the forum a few months ago.

With those Tas Tab ratings, I divide them by 10 to get a weight rating. In other words, if it's a rating of 645, I convert that to 64.5 kgs.
