Sniper pistol combo firerate

[Gibstick]

[SELECT ALL] Code:

bind MOUSE3 [if (= (curweapon) 7) [attack] [secondary; attack]]
bind MOUSE1 [primary; attack]
bind MOUSE2 [ if $editing [ showmenu editing ] [ altaction ] ]

Press MOUSE1, MOUSE2 three times then MOUSE1 twice.

Using this script with an added bind MOUSE 1 [primary; attack; echo (millis)], I calculated the time between the first millisecond echo and the last. I got 1495ms. Nowhere near the 240ms of the subgun.
