Deviation from straight-line route?
Hooks? (Is what I usually say)
Alas, I had spaghetti. Bananas are better.
A hook is different from a banana. In a banana one starts running in a slightly different direction than ideal and gradually corrects back towards the control. Time loss is small unless the original deviation causes confusion and hesitation. In a hook one gets close to the control and has to make a dramatic change in direction upon seeing the flag. I had some of both, and a few were big enough that my time loss is certainly more than what AP shows for the course.
Thankfully no spaghetti. I don't like spaghetti much anyway.
I've never heard the term banana before, but it makes sense... I had examples of both bananas and hooks on the middle course.
I do both bananas and hooks! Great and perfect terms! unfortunately usually a spaghetti or 2 as well.
The best spaghetti is the straight uncooked version.
The banana is an interesting psychological phenomenon, where you figure out that you've been going the wrong way, but can't convince yourself to correct all at once, and only gradually change direction. As if you were some huge tanker ship with lots of momentum.
Sometimes I "banana" intentionally. But I guess in those cases it's called "contouring".
