I was doing the math and 90-100% is probably too over powered. You could do craft missions almost infinitely and would rarely have to dig at all. But just over 50% would essentially give about twice the productivity for the same mats.
All rounded down: 396/2=198, 198/2=99, 99/2=49, 49/2=24, 24/2=12, 12/6=6 and 6 is close to the minimum number of mats to craft anything.
198+99+49+24+12+6=388/396=97.98%
