The lurve score becomes more difficult to see grow as you accumulate more. Each individual jelly can only give 100 lurve points to another jelly. Once I’ve given you 100 lurve points, then I can still continue to give you GAs and GQs, but they will not add to your overall lurve score.
Having said that, it’s a fun, silly little thing to watch grow. I think it’s healthy to hope it grows, because that means I’m interacting with new jellies whom I might otherwise miss.
To answer your question directly, I don’t know. I’ve never counted.
