To clearly understand the expected behavior and possibly clean up the implementation, the dependency of this is to add more tests/examples of `Lt` and `lt.py` in general, I'll work on...

What's also weird is the subscript for 2, probably this is a lead. I've checked the code to specifically handle `atan` and `atan2`, they seem harmless.

The preset functionality should not be removed or at least should be implemented in a new way. It's a shorthand to create frequently used GAs. We can deduct the behaviour...
