Results
 

Since I began testing the new 2.1 update I have run 120 races using the same guidelines I posted before.
I have these results from the top 4 RX:
Win 108 90%
#1 35
#2 25
#3 27
#4 21
Exactas 81 68%
#1rx in 55 win/place with #2-3-4 46%
#2 rx in 20 win/place with #s 3&4 17%

My betting for win is to play any Top 4 RX horse or Horses that is3/1 or higher
in a dutch.
I have hit 50 wins or 42% of these dutches.
