Great route and great execution!
Questionable on the route...but thank you :)
The only area I think one could quibble with is the start finish, where I would have voted for "go all in! clear!" but you baked in a few more options, which would have still paid the bills at: your actual speed (5 minutes to hunt for 50) or your speed plus like 1% (360 minutes = another 3.6 minutes = 8 minutes @ 50 = clear).
And they are really good about making a mess of getting into and out of the start efficiently, so hard to optimize much better anyway.
