Worcester, 13:45: King Alfonso
I haven't looked at this since then but newcomer seems to be doing very well from this kind of angle, well donethese threads get little interest unfortunately. There was a discussion on here a few years ago that had an in-depth post about trainer changes ... its something that comes up a lot in the USA racing because of the number of claiming races .. some trainers do well when they are running first time for a new trainer, others take two or three runs before they have them dialed in.
edit : Just found the thread i was referring to, some good reading here. No idea if the same numbers apply, but probably worth dragging up and updating.
I'm sure many of you have looked at this angle before and there's various variations etc that you can apply, but I ran a report for data 2000-2017 to show me the £1 LSP at ISP for horses getting their first run at a new yard, and here are some of the more likely looking trainers. I haven't...www.theukbettingforum.co.uk
pawras was involved in the initial findings, did you ever follow this up pawras ? Anything interesting thrown out there?
Do you allow multiple runs? I.e. starts off with Trainer A, moves to Trainer B and then has x number of runs in the 6 weeks after the trainer change?The jumps system is the most simple one. Any yard, having had a previous run for another yard in the last 6 weeks, is profitable (75% ROI to BFSP over 10 years). I try and avoid trainer-based criteria unless I think there's good reason. I quite like the Max Young yard and 2 or 3 of them have been heavily backed and it just hasn't happened.
Wouldn't know re that software I have my own bespoke thing, I just wanted to be clear on your criteria. This is what I got for about 20 yrs worth of data to isp.No, just the one. Not sure how I'd code that in HRB except to manually do it or add another system (eg 1 run, then <6 weeks since last run). Generally, I've found allowing trainers 2 shots isn't profitable. 1 can work, or they need a few goes in which case you're just keeping a general race reading eye?
Thanks pawras, really interesting. To clarify, I use that for national hunt handicaps (between 7 and 42 days) with a basic odds filter of 3/1 to 33/1 on morning prices as a guide. I think those filters would hopefully make the chase and hurdle hcap results a little better.Wouldn't know re that software I have my own bespoke thing, I just wanted to be clear on your criteria.

First run with new trainer so long as it's within 6 weeks of the trainer change.

So I can see how bsp might show a good positive for chase and hurdle hcap, but with those sort of strikes you could easy be looking at some big losing runs.

For flat and all weather, that just doesn't work and I refine further. On the flat, I focus on young and unexposed horses (idea: new trainer sees a trick not yet fathomed) and on the AW I focus on a few different things. Guilty of backfitting and happy to share privately, but both profitable on testing here so far at least.
