"Take Aim" Clarification, Sniper Rifles and Magnification Options

[DnDer]

This should be pretty easy.

Rules say that you can only "take aim" equal to half your relevant firearms skill. Sniper rifles using vision magnification must use a "take aim" action just to lock onto a target before they can shoot, but CAN take multiple "take aim" actions for the bonus.

For this example, we'll say my Longarms skill is 6.

I want to snipe someone with vision magnification. I may only use 3 "take aim" actions to accumulate the bonus associated with the action. Does the "take aim" action required by the vision magnification count as 1/3 of those actions? Or is it the bonus merely max out at half your skill, no matter how many "take aim" actions you use? (ie, I can take 100 "take aim" actions, but will never get more than +3, for my example.)
