The auto_concjump alias goes like this (the auto_grenjump is similar):

// Concussion grenade auto-jump with countdown. FOR MEDIC AND SCOUT ONLY
alias auto_concjump "primetwo; exec timer.cfg; wait1sec; wait1sec; wait1sec; 
wait1sec; time; +forward; time; +jump; wait; -jump; wait; wait; -forward"
bind v auto_concjump

The wait1sec inserts a pause in the script. It is defined in the autoexec.cfg 
as wait25 (or a wait command repeated 25 times). The autoexec.cfg holds aliases 
for wait to wait35

The time-alias is an adjustable wait/pause in the script, so you can fine-tune 
the pause before the jump in several lag settings.
The time-alias is adjustable with PGDN. You can assign values of time = wait 
(one wait) to time = wait35 (or 35 wait commands in a row).

Before you join in the battle for the flag you should make a test auto_concjump 
to see if it needs adjusting. 
Should the range of time be too much or too little you can also adjust the 
wait1sec-alias in the console 
(example 1: alias wait1sec wait20     instead of the standard wait25).
(example 2: alias wait1sec wait30         "    "  "     "        "  ).
But don't forget to re-adjust the time-alias with PGDN after such an adjustment:
don't leave the time = wait35 on when you just adjusted the wait1sec to wait35!
