If you bet two horses no problem, you end up with the 2 and 7. FTL wanted to go farther and narrow it down even more.
First of all the 5 and 7 are 1-21 and 1-32 respectively, pretty much showing their total lack of consistency. The 2 is 1-9 lifetime and has not failed nearly as much as the other two, but there is more!
