[Solved] PR ratings not calculating correctly
Grateful if you can check the calculations behind the PR odds.
for example Tramore 17.45 Fuinseoinges Fire showing 6.7 with setting at 55, but Betfair odds are 42 back 240 lay.
This is the 5:45 at Tramore as downloaded about 8:30am today, Bonarc is the odds on fav and has been pretty much all day he also ranks very high in loads of other stats but according to PR ratings he has less than 1% chance of winning ? Also Fuinseoiges Fire is the Pr top rated it is currently 100/1 ?
I have been seeing this for a couple of weeks now, so I think there is something not adding up correctly.

@mikeywilding Another strong example of issues with the PR Ratings, this is the 2:25 at Newbury today downloaded about 11:30 this morning.
At first glance it looks ok until you look at Orbaan and Jahbath both have very good records at 1m and are joint 3 fav , yet Jahbath has 0% chance of winning according to PR ?
I know your looking in to this but for me this is a big problem as I use the PR stats as my first check on any race and it appears to me to be broken and has been for about a week or so.
Please help me Michael, your my only hope 😉

@mikeywilding Hi Michael, I think I have worked out what is going on with the PR ratings, I have exported my usual race card that I use twice, and horses have moved around a little on some races so I then compared the export sheets to the live race cards and it would appear that for some reason it is not applying the public odds factor onto all the races when you export the data I have mine set to 55 but it looks like it randomly only applies about 25 and lower to some race cards which which would explain why you can get a fav in the betting at the bottom of an exported PR rating because it either hasn't applied any public odds factor or only a very low factor but what I cant see is a pattern, it seems to be completely random on which races it affects.
Have you had a chance to look into it yet ?
@mikeywilding Just exported today's races and all looks good, the export sheets are like the data stream form the Matrix to me, Its just a sheet of numbers but I see patterns and the glitch is no longer there 😊 😎 😀 🤗 😎
Whilst we are on this topic, can I assume that the PR Contenders as marked in historic data are those calculated at or near to the start of the race? I ask as some contenders change, certainly from exports the night before a race, so I assume that they change nearer the off as well. Thanks
