Woolf121,
Could it be there are more "triers" in races than you are willing to give credit to?
Perhaps this gives rise to the "inconsistencies" you mention?
Do Barcelona (football) win every game they play? NO
Does the fastest F1 car win every race? NO
Likewise horse racing….it’s called sport and the variables are many.
Getting a horse physically fit and mentally tuned is one aspect, finding the right race conditions (going, trip, track) is another. Add in a slice of luck and you might be competitive in said race.
To suggest its point, click, bingo is well off the mark for the vast majority of races run in the UK.
