I don't know the events you're talking about but the MAIN reason has got to be interference in races &/Or a rise (albeit slightly) in class ..... or just really crap dogs.

You can't have a FORM turnaround of 6 to 10 lengths in the dishlickers if they're reasonable dogs unless ..... checked at start, up in class and more competition in the run to the post first time around ...... (then I'd believe 10 lengths 'coz thye wouldn't have a clear run early and would have a wall of dogs infront of them down the back) ..... other than that ?

Times on their own are a bookies Superannuation Fund ..... phhhhtttt
