Your first error is stating "completely acceptable" and "perfectly acceptable".
Regarding whether the VB is outside the weep flange or under it, it really doesn't affect its performance.
Your second error is stating the above "doesn't affect its performance".
The above three errors (the first error is two related errors, but still two different errors) combined with other errors shows the errors of your thinking quite clearly.
"Overkill"? To do it correctly?
I guess it's the difference in jumping out of a plane and wearing a parachute or not wearing one - the fall is basically the same, the parachute "does not its performance" (the fall) much at all.
Not until it is time to open the parachute does the parachute have any effect, at which time the parachute makes a significant contribution to the intended and designed outcome and performance.
