I think it might be nice to record somewhere highest positions achieved in ladders. So players can compare. For tie-breaking we might also record for how long the position was held in time or in challenges repelled.
Realistically probably it would only make sense for sidewide ladders.
This information isn’t available anywhere at the moment, it’s a little sad.
Of course, it would need to be a separate table for this, and figure out design, and ladders aren’t high priority. Simpler solution: give medals for reaching high places in ladder. We already have system and design in place to give these, shouldn’t be hard in the ladder code to give it, if a player doesn’t have it yet.
