Stix, I could be wrong but I have doubts about the accuracy of the CF and Tim categories for horses having their second run from a spell.

Your statement of points/% between top 2 rated :- the CF and TIM categories can often be puzzling in their allocation of points. Sometims the extreme generosity of TIM to a certain horse against all others in today's race could easily be interpreted that it must have set a world record at its last start/s and is now a moral to win - but it often does not happen.
