Well Geezer, we all know, a little pressure behind a leak, is easy to cap & fix.

The more pressure 9GAS) behind it, its harder to cap.

So if there is enogh pressure from a LITTLE leak, thatneeds
to delay Flow test by 1 week, then its possible pressure from a great amount of GAS, causing it delay 1 week to stabilise & fix, before flow testing.

I can see the $$$$$$$$
