I think there’s a bit of an issue with the philosophy behind this.
Whilst a section of quavers sounds great at say 80%, this does not hold true at all for semibreves, and they drop out way too early.
I get that there should be some gap between normal notes, but it needs to be more an absolute gap rather than a percentage gap. I was wondering why my tied semibreves (2 bars) were cutting out half way through the second bar.
So I turned it up to 100%, which works fine for horn pads, but no good then for faster bowed passages in the violins.
It’s almost like this could be set based on a technique text, e.g. marcato vs staccatissimo etc etc. in addition to the dots (staccati) and lines (tenuti)
