I'm sure there must be a rule of thumb in working things like this out?

1) As DCLUCIE says, past results. £X,XXX,XXX.00 based on say 1st to 3rd last year with a sliding scale down to the same positions up to 5yrs previously. The same formula taking into consideration the next 3 positions and so on?

2) The same formula based on positions in a World Championship.

3) Again based on a National Championship

4) Centre Championship

And so on. The greater the status of the championship, the higher the appearance award.

If it was transparent then there could be no arguments.

Ex gratia payments to riders would not be neseccary as they would have proved themselves worthy at one of the above levels!

There may be issues if say, David Knight fancied a go, but it should be a Road Racing championship to count!
