Hello again,

You are right. It depends on the server. In the case of FA, they are currently using a server version called ET:Legacy. In order for TrackBase to retrieve important and relevant information from the server, the owner would need to run a version called ET 3.00 - TB 0.x.x (https://filebase.trackbase.net/et/server/). Whenever a player plays on a server like that, we can calculate their TBP (TrackBasePoints) rating, or skill rating. It was introduced to benefit everyone with a few fixes from the older ET 2.60b (from 2006) and implement more tracking statistics such as accuracy or revives, other than just receiving XP, possibly only by 'xp whoring' med packs or ammo packs.

It is the sole decision of the server owner which version to use. FA have used ET 3.00 before, thus likely you did have that still in mind and wondered why it suddenly disappeared 'working'.
At any time you can check our server list (https://et.trackbase.net/serverlist/) and see which server is supporting TSP rating (star instead of number, as shown in the legend below the list.

For sure it is always a better idea to look on the Skill Toplist (https://et.trackbase.net/toplist/) rather than just the normal Ranklist (https://et.trackbase.net/ranking/) to find the players who are really good, in all terms and not just at receiving XP. Yet again, it's the decision of anyone hosting a server to choose from which source it should work.

If you still have any questions regarding the TSP rating, feel free to search our forums for older threads or reply to this one.
