I certainly don't mind doing some testing though to be honest I'm still at the stage of breeding and getting the combination of stats I want. I had a HD crash and needed to reinstall my game. Unfortunately I didn't have a back up of my dat files on my work PC, just the horse files for CK testing (well it's a work PC and I wouldn't want someone to find too much evidence that I'm playing games though it's mostly over lunch/break times). I've had to restart breeding and I thought I'd start with the 10-16f mark as I had been doing sprinters till the crash and will redo them at some point. Believe me when I say the game files are now backed up in triplicate

FWIW I ran your horses through the CK against the horse files I had a few days ago just to see. IIRC and please correct me, you're off league standard times on the horses I downloaded.
I'll simply refer you to a previous post


That's where I'd gotten too for the 1m and under distances and where I'd expect to get to again once I start breeding those distances again.
Of the current batch I'm doing between 10-16f I've really only been testing 3 yr olds at 12f and at that stage I'm running off league standard pace by 0.5s. I think at 4/5 yrs of age they probably would be around league standard and of the one I did bother running to the end of his 4 yr old season that is the case.
I'm more than happy to trial a few horses and post results here if folk post horses to race against or to send the results to you in private if you prefer.
