Altered ranking and its effects, SL Options

[Ragnar_40k]

With the new update the ranking has changed slightly. Here a little FAQ with explanations why and how:

SPM = Score per Minute
Non-PB = Server w/o cheat-protection, e.g. w/o PB or w/o an up-to-date ETPro.

Currently for most of the players the ranking increases. This is the result of the exclusion of non cheat-protected servers.

Q: Why does this impact my ranking?
A: The ranking is calculated relative to the average SPM value of the maps for all players. With the change the SPM-data of about one quarter of the servers is now missing and the ranking adjusts automatically to the new values. This adaption also happend in the past (daily), but the changes were only marginal. In 2-3 days the ranking should be consolidated.

Q: Why does the ranking increase for all players?
A: The ranking is based in the SPM value for each map. Currently the SPM is dropping (e.g. Oasis drop from 7.22 tp 7.09 in one day). One reason might be, that servers w/o anticheat produced a higher SPM value (I wonder why?). This is also the cause for the efficiency increase in the player statistics, since the ratio between player SPM and map SPM increases.

Q: Players from Non-PB servers are still ranked!?
A: That is (partly) true. We don't delete sessions from Non-PB servers or recompute the statistics. But these players wont get any new data from Non-PB servers. Unless they play on PB enabled servers, their rating time will drop as if they weren't playing at all. When they drop under the 5h limit, they don't get ranked anymore. The entire process will last about 14 days.

Q: Why do you compute the "SPM ratio", isn't that pretty complicated?
A: The SPM differs for all maps (as you can see here), so you can only compare maps when you calculate the ratio between the player SPM and the map SPM (i.e. the avarage SPM for all players on this specific map). With this ratio you can compare player efficiency across maps.
