It's my understanding that whether you use Hypercharge after the pull like that (to really ensure that nothing is wasted), or you do it in the prepull period, the duration of the vulnerability debuff is the same. Since it's the turret shot itself that refreshes the debuff - if you get 5 shots within Hypercharge in both cases, the duration of the vulnerability debuff is the same.

But you're right that using it after the pull like that will absolutely guarantee you get the maximum benefit, it's insurance against slow tanks and what have you.
