That "enormous bias" could also simply be that someone is using polar coordinates a lot. It's hard to not encounter rho and theta in literature about it... That's just one example, Greek letters have been used in science for a very long time and I personally find code that uses the same notation used in literature easier to reason about and much more pleasant to read.
