Digging skills improves digging yield

[Russmaster2299]

I find it a bit weird that excavating a block only yields half of the actual mass, but I can see it as a form of balance. However, I think there should be a bonus to the digging skills that improve the yield.
Maybe something like:
Regular/hard digging = 50% mass collected
Superhard Digging= 75% mass collected
Superduperhard Digging= 100% mass collected

Alternatively, make it so each point a dupe has in excavation adds an additional 5% yield (up to a maximum of 50% yield, and no lower than 50% yield.)

there is a mod that improves yield with higher digging skill, but it'll likely never make it into the official game because it encourages hoarding valuable resources until you have high skill level instead of using them, which slows down the game.
