@leopard the code may be similar, but LocalRatings (the mod) and Replay Pallàs are independent from each other. So, any change to the mod does not affect Pallàs.
LocalRatings (the mod) has a filter menu where the minimim number of matches can be set, as well as other filters.
Without having checked myself, I guess Replay Pallàs shows the results with a default combination of filters (as well as a default combination of weights).
It probably makes sense that Pallàs uses one default choice: switching from a combination of filters to another implies recalculating the leaderboard in some cases (not when the minimum amount of matches is changed, but for other filters).
LocalRatings (the mod) is already case-insensitive. This was implemented not long ago, so I assume Pallàs is based on an older LR version.
