Thanks for that Try.

Like all stats , its a starting point , just like Ratings are.
Ratings on their own usually show a greater LOT than those shown here with the Pre-post market.

Its the filters one uses that can put them into profit.

When I did the exercise some time ago on 30,000 races.

Its SR was approx 80% Top 5

LOT -5%

The sample I did had the fav at 30%

Interestingly, the 5th fav had the lowest LOT at the time.

Our live market results for the same races ,at the time showed a 85% SR
for 1-5 favs

Your sample shows a small loss of -7.4% LOT
Which is not a bad result.
Delete the correct one & your in profit.
If one ran a 2nd sample of the same size , the SR may be similar but divs will change resulting in the 5th Fav & 1st fav possible showing a negative figure.


That remark...
"Your stats are meaningless."
That's plainly RUDE.
It gives the strong impression that it was intended to be insulting.

That's the type of input that turns possible posters right off!
Some decorum & humility would be in order next time.
