Ventilation under & above windows

[Space Race]

Looking at using board on board vertical cladding with a ventilation strip/mesh at the bottom and top of cladding.

I'm struggling to find any examples of how these vents are detailed under and above windows. 

To form a vent over the head of the window seems easier (much like at the base) but I've not found a single example for under.

Is this not done? Am i overthinking this

If anyone can point me in the direction of ventilation details above and below windows that would be much appreciated

I used the aluminium vent strip the 25x50 strip with all the holes in, this is finished on top of the cladding with a small gap between this and the overhanging window cill.

Normally you will leave the battens short of the window opening so the air can flow round.  Like this:

How small was the gap?

I was thinking the (vertical) frame timbers would be fairly snug up to each side of the window but actually they could stand clear. Then my vertical battens would be spaced as you show. Thanks!
