My first choice for taking out a command got me ALMOST to the end of the puzzle. I had to invert the function calls in the "second half of the recursion" function to make it get to the end, which makes me think there might be a puzzle layout that neither solution would work in. But it made it.

beaza: There are at least two ways to get a solution of length 13.

If I understand your solution description correctly, I think you can just remove one of the commands as it is not needed. You may need to think carefully to see why it isn't required, or you can just try all the commands one by one to see which it is. :)

Alternatively there is a much simpler length 13 that uses 5 functions instead of 4.

There is some kind of obvious optimization... obvious to everyone else... that I am missing. I just did this one and the "first sequence" one, and each solution is +1 steps over everyone else's lengths. Also, I don't see how anything I have is optional.

I have two color conditionals and three "start next iteration" commands in F1. I have three commands in each of the other used functions. The color functions look the same: standard two-function recursion, and a "what if we were not really on the last sequence" restart. The last function is the other half of the two-function recursion, sharing usage for both of the first halves. What's a hint about what I am not seeing? Even just telling me the function that is one step too long will let me search for the reason. I'm sure I have an "oh what an idiot" moment coming to me, but oh well.
