The issue seems to come and go accross a single game. Interestingly, it seems the axis percentage is sometime gone, and sometimes both percentage are gone (but never the allies percentage alone). Since the allies percentage is computed on the basis of the axis percentage server-side, it looks like the win percentage is correctly done at ant time, but the values aren’t always sent correctly to clients for display. See CG_ParseSkillRating() for the client end. This looks like some sort of overflow happening on the server end just before sending the values (maybe when server is highly populated?).

In any case, the win percentage is done correctly. This is only a minor display issue.
Possible solution: increase buffer size in G_SendSkillRating().

Actually not fixed. The issue seems still present with a high number of players (30+ connected).
Either the buffer wasn’t previously increased enouh, or it’s something else. (note: it’s most probably something else...)
Edit: The max length of a string passed to Cmd_TokenizeString is limited to MAX_STRING_CHARS (1024 char) anyway, so increasing it client side won’t do much(?). Instead, try optimizing what is passed and when it is passed:

  • optimize by sending whole rating directly instead of mu and sigma. These value aren’t used client side in scoreboard/debriefing anyway. (done already).
  • optimize by sending delta rating only in intermission. These values aren’t used in in-game scoreboard, only in intermission. (done)

Code has been optimized, and I cannot reproduce locally anymore (with 32+ bots).

Reopening. Looks like a similar issue happens with SR display client side (same code as map bias is used to send the info to clients).
Closing, the issue isn’t client side (see #403 for more robust code commits).
