In reply to what you write about in your work ups
I enter at least 1 line for every horse, There are tools in RDSS that separate
the horse by groups but I like to rate all the horses
I let the win probability number of RX 3 show me not only the RX3 rankings
I use the probability numbers of RX3 to make final decision on my win contenders
Horse 5 and 6 have 33%, The higher the probability number the more likely the winner .
In this race horse 1, 4, and 5 are win contenders based on their pacelines
and your guidelines ( my flavor)
Horses 2, 3 and 6 are not win contenders
Horse 5 and 6 have a big advantage in win probability percentage of RX3
They each have 33%. However I marked horse 6 as not a win contender
In this race my two win bets were horse 5 and since I have doubts about the 5 moving up to win again I also went for better odds and bet the #1 horse
with 14% win probability
