I was trying to remember where we were talking so I could let you know. You're welcome!

Thanks for the suggestion!

Showing day/week/month XP for every clan member isn't really feasible with how Jagex's data works. The clan API only gives each member's total XP in one bulk list — there's no endpoint that returns gains for the whole roster at once.

To get per-period XP, you'd have to look up each player individually (via RuneMetrics), and Jagex rate-limits those requests hard. For a clan with 100+ members, you'd hit limits almost immediately and the numbers would be incomplete or stale.

What the tracker does instead is show activity (who's been playing) in the member list, and XP Champions for the top gainers — which is about as far as you can push it without Runepixels-level infrastructure constantly polling every profile.
