Knoeki,
%pt.total.nicks and %pt.mode.count.1-6 did not get
declared as local variables with the var command.
A call to a variable that is not set or declared
is set as a global variable by mIRC. The first time
that an undeclared variable is incrimented mIRC will
set it to 1 (one) thus the following three lines
give the same results.
inc %tmp.nick.count
set %tmp.nick.count 1
%tmp.nick.count = 1

"...how is it even relevant to this script at all?" output => spread across $+(,$calc(%pt.net.count - 1),) networks this counts servers => var %pt.net.total $scon(0) many chat visitors wont know the difference between servers and networks so i guess its ok to use either term in this type script. The only people that need to understand the difference between $server and $network is those who script the client and are concerned with multiserver issues. Even when taking into account that this snippet counts disconnected servers and unjoined channels there is still a few count errors.
