only the pinging system is related to this value
if the pings fail for 30s then it disconnects the player
If he raises it over 30s... then simply it will ping more time and game will accept bigger delays

I wonder how it's possible to fail to receive 30 pings in a row o-O (apparently it pings once per second)
