The top two tiles at the Leaderboard are Most SP (Learners) and Most SP (Tutors). While I can understand why SHW might wish to distinguish the people that have a lot of SP primarily from attending sessions from those with a lot of SP primarily from hosting sessions, I think the distinction is unclear and confusing.
I've added a view of the tiles when I select All Time. If I look at Long T, the user with 31,024 SP in the Learners category, their profile (https://schoolhouse.world/u/379578) identifies them as a Tutor, says they have hosted 177 sessions, says they have attended 0 sessions (it's conceivable age restrictions mess up this count for me, though I'd consider that a bug if so), and have 5145 Super Helpfuls. Why is this user in the Learners category? And why don't their 5145 Super Helpfuls put them at the top of the Most "Super Helpful" Ratings tile?
The next user in the Learners category, Jessica W, appears to have deleted their account (https://schoolhouse.world/u/jessicaw028 returns an error page), but given they are shown as 8th all time in Questions Answered, it sure seems like they are (or were) a Tutor.
The next user in the Learners category, Naya S (https://schoolhouse.world/u/nayaa), has been a Tutor since 2022, has hosted 378 sessions, and attended 281. At least there's a large number of attended sessions here, but it's still unclear why putting her under Learners makes more sense than Tutors when she has hosted more sessions than she has attended.
Certainly there are lots of Schoolhouse users that are exclusively Learners, and others that are exclusively Tutors, but there are lots of users that are both. E.g. a student taking Pre-Calc that also tutors Algebra 1. I don't think the Learners vs. Tutors distinction makes a whole lot of sense when the users near the top of the Most SP (Learners) category are clearly Tutors. If there's no reasonable way to distinguish the categories, I'd expect them to be grouped together.
I'm assuming Long T being considered a Learner is why his 5145 Super Helpfuls don't show up in that Most "Super Helpful" Ratings tile, but that's a guess, and there's no information in the UI that explains to a user how these judgments are made. I don't see why the Tutor vs. Learner distinction should impact the Most "Super Helpful" Ratings tile.
I think a lot of these tiles would benefit from a helptip icon with a tooltip on hover that explains how the calculations are done. As I've also noted at https://schoolhouse.world/feedback/p/certification-count-on-leaderboard-is-unclear, it's confusing in a number of areas how the calculations are done and then what filtering exists to put users in Learners vs. Tutors categories and also exclude some users from certain tiles (like Long T from Most "Super Helpful" Ratings).
I checked my settings (https://schoolhouse.world/settings) to see if there's some self-classification we make of whether we are a Learner or a Tutor but didn't find anything.
I would have submitted this as Feedback and not a Bug, but the Category options for feedback requests has changed since I last submitted something, so I'll go with Bug, as I do consider the functionality to be at least somewhat broken here.
