While reviewing the Esperanto morphological libraries (T197240), I found a few errors in my analysis code that conflated post-analysis types and pre-analysis types, which led to some obviously absurd stats on very small numbers (like 137% of types being affected by a change). Previous analysis percentages were thus incorrect, but probably not by too much in most cases.
The primary goal is to fix that counting error, though lots of other little fixes and improvements will come along for the ride.
