I'd like to see a closing bet time for every race too. I'm sick to death of watching the jump prices of winners shorten AFTER the race.

Yesterday I had a win bet on r8 in Brisbane on a $9.70 jump price runner [Stab] that went down to $5.50 after the race was called. The fact the horse won was no compensation as when I can, I judge my bets close to start time as 'value' [bet] or 'no value' [no bet]. Getting caught out holding subjectively judged poor value bets win or lose, is poor punting.
As I rarely back favorites, 'top fluctuation' from bookies is [usually] a waste of time. Stab overall generally pays better odds on longer priced runners.

I'm not a Betfair punter, but I'm starting to seriously think about it.
