Quick question:

Is player's pre/post think (FM_PlayerPreThink/FM_PlayerPostThink) fired every time the player gets updated (sends packets to the server) or is it fired every server frame? If not, is there another way of detecting the update rate? (maybe by using FM_CmdStart/FM_CmdEnd? Querying commands won't cut it.)

it's fired at every frame the CLIENT has, not the server

1.Client sends a message with protocol "clc_move" (#define clc_move 2) to tell server that he has to run movement code.
2.the server-side engine will call SV_ParseMove, SV_ParseMove will call SV_RunCmd for multiple times.
3.SV_RunCmd will call itself recusive recursively for multiple times.
4.SV_RunCmd will call FM_CmdStart, FM_PlayerPreThink, FM_PlayerPostThink and call "PM_Move" to run PlayerMove code then finally call FM_CmdEnd in SV_RunCmd.

5.if it's called from SV_ParseMove for more than once, or recursively, the gpGlobals->time will be the same in the later. so you can compare the current gpGlobals->time with last saved gpGlobals->time and wait until gpGlobals->time changed.

example:

PHP Code:

new Float:g_PlayerCmdTime[33];
new Float:g_PlayerUpdateRate[33];
public FM_CmdStart(index)
{
  new Float:curtime = get_gametime();
  if(curtime > g_PlayerCmdTime[player_index])
  {
    g_PlayerUpdateRate[player_index] = curtime - g_PlayerCmdTime[player_index]
    g_PlayerCmdTime[player_index] = curtime;
  }
} 


if g_PlayerUpdateRate[player_index] is less than 10.0 / 1000.0 (10ms) for more than 5 secs, this player is likely to be a cheater who is changing the game speed.
