Tap, tap, tap, tap, tap, tap...

or

Tap 2-3-4, Tap 2-3-4, Tap 2-3-4, Tap 2-3-4, Tap...

or maybe something in the middle? Does it seem to make a difference to you? Or do you just tap more or less rapidly depending on the intensity of the situation? Should we all be buying stock in replacement space bars?

For the health of my keyboard, although sometimes I get a little over-excited!

I don't spam the space bar.
I use autofire, set to disable on target change.

I constantly just mash away at mine. I have fire all weapons and distribute shields bound to it, so there's no reason for me not to :p

Use my keybinding and a 1-2-3 slight pause 1-2-3 slight pause 1-2-3. 3 round bursts of use.
I just wish the game could keep up with the button mashing.

Yeah . . . this is what autofire is for.

I usually mash my spacebar to the baseline.

da nana -spacebar- -spacebar- -spacebar- -spacebar- da nana - -spaceba-sp-sp-sp-sp-sp-sp-sp-baaaaaaaaaaaaar-

I have autofire, but I often have several skills also bound to space so its in my interest to keep hitting it.

A macro on my g15 that just spams my fire all beam weapons key, in this case the ".". I have the M1 Key set for this so if I need to quit firing I just hit the button again.
