The curious thing is that from her perspective, she was only swimming straight the whole time, and only expending energy going straight. It was the 'gifted' energy of the tide that caused the oscillation (from our perspective).

Just struck me as interesting to think that from her point of view she was swimming as straight and as efficiently as was possible.

You could imagine a coordinate system in which she took the shortest path, yet the projection in our system doesn't look like a straight line

Non-euclidian swimming, my favorite

It likely was the most efficient energy-wise, why waste energy going against the current when it'll undo itself anyways.

An aquadesic line, if you will
