Crash, these days I'm always trying NOT to impose hard and fast mechanical rules.But obviously i'm getting something nearly right but not quite.On the question of race classes and types, I think this could be the problem as I do get confused with the comparison here., not in the general sense, I mean I know the difference between Octagonal and Thunderhawk, it's when the difference gets closer that I fall down I think (in Australia that is, in England things seemed to be much more clealy defined, although that might have just been familiarity on my part)

But for the excercise I will do a study and see if I can see a pattern.
I did notice my selections in races 1&2 showed a loss, whereas my selections race 3-8 showed a profit which was enhanced of course when 1&2 were left alone. But I felt that this was getting close to retro fitting again, what do you think? (any comments welcome)
