Hi Mitch
I agree with you, That 91%,? I would need to see the records myself to go with that figure blindly.
No two peoples records will ever be 100% alike. Everybody looks at things their own way. We all make judicial decisions on race types, class, surfaces field sizes, etc.
I just took a random 315 race sample from my Santa Anita spreadsheet.
I just grabbed 315 races from various parts of my total SA spreadsheet. I have every class, distance, surface, age, field size represented.
because I record the winner of every race run every day.
In my sample of 315 random races, using FTL's guidelines
to my own interpretation, ( I add a touch more Brohamer)
The winner of the race has a + or (+) a zero 222 times
from the last line or 2nd line if the last line can be excluded.
The percentage is 70%
But these stats include every factor class, distance, surface, age, field size
and are track specific (Santa Anita)
What I am saying is the best way to answer the opening posters question is
"make your own records and be consistent in your own work"
