Jim, you may very well be right about the advantage gained in RG's, which I've avoided like the plague since I've been here...played one last year if memory serves...I just don't see the need for the top players to use a program like this. Now with newcomers, low-level sandbaggers and the like, might be a different case.
In the case of the top players, it doesn't seem to me that this program is doing anything they aren't already doing as far as intricate calculations and such. Maybe it offers an advantage as far as dinging, I really don't know.
There's much irony in their disclaimer, something to the effect that it's only to be used for "fun games" but not games for credits. In the end I think one probably gets what one pays for in more ways than one.
