Congratulations on your TAS!
I actually have a copy of pretty much the same set of notes about those races in
this previous rejected TAS thread. Also, the distribution is actually uneven: you'd think you'd be racing through all 16 tracks four times through each of the four variants. That's almost correct, but one of the tracks is never driven through in the opposite direction. Subsequently...
- Blaster is raced through five times, two of those in the opposite direction. The twelfth and 60th races are duplicates of each other if we only count the forward/backward/bales of hay variants (since this is forwards with bales of hay).
- Cuttoff Pass is also raced through five times, two of those in the opposite direction. The 21st and 43rd races are duplicates of each other if we only count the forward/backward/bales of hay variants (since this is forwards without bales of hay).
- Boulder Hill is never driven in the opposite direction, and thus is only used twice: once with bales of hay, and once without bales of hay.
