Results from a week of the 2-2-1 angle
 

I found 18 horses eligible to be played the next time out from the charts.
Of the 18, there were 6 winners,8 places,and 10 shows.
Net profits from $2 ACB-58.00 from win,29.50 from place,and 21.50 from show for a total of 109.00 over a two week period.Even without one winner,it still showed a 15.00 profit.
The 2-2-1 is when a horse stays the same for the first two calls,improves by at least one horse for the next two calls,then improves from the stretch to the finish thusly:6-6-5-5-3.
The only horses which are not selected are those who are 3 year olds vs older,those whose odds in that last race are below 3-1,and those who today are racing for a purse more than 50 per cent higher.
Now on to follow the losers for more data.
