Here is a snapshot/printout from my software for Race 1.
Looks like there is a clear separation at the first 1/4 for the 2 and 3. It looks as though the 3 slowly declines in energy, whereas the 2 has some left in the tank late.
Underneath in exotics, I typically will use the top pace, in this case the 3, as well as any big 3rd or 4th quarter sustained move.
In this case, I'd use the 2 big last 1/4 moves, the 4 and 5, and for smaller exotic plays, I'd add in the 1-6-7 for 3rd.
Exotics would look something like this...
$2 Ex 3-4-5 / 2
$1 Tri 2 / 3-4-5 / 1-3-4-5-6-7
For a total investment of $21
