Can only see it being useful for custom work in that area
With what wdkugdn does in there, I would say changing the psi that it is dealing with is custom work.
I would agree that messing with it might not be necessary for most and would only be a minor change anyway.
But, the further your cracking psi deviates above the calibration, the more important it may become.
If I get bored I may have to try the 100% thing just to see what it does.
My guess is as long as wdkugdn is larger than the actual point of restriction, the only thing it might affect is wear and tear on the tbody.
