Some geeking for the night-o at the corn maze.
The spreadsheet below has the optimal route and distance saved from skipping that control. Only taking into account skipping one control in a row (for example skipping 5,6,7 may have been better than skipping 3 individual controls but since I had one skip, I only looked at the individual controls). The distance is utter nonsense but at least it should be consistent.
Result: 8 is by far the best skip, followed by 5 and 10. 9 and 14 are the worst skips saving you one straight away.
