the mack/ret > skiff/proc yield does indeed come from utilising the extra low slot for an MLU.

also, 2x mlus is 1.09^2, not 1.09*2

max skills, with a perfect orca bonus, using one 3% implant gives you... *opens excel*

5496.238524 m3 of ore every 121.78125 seconds.
then we must account for truncation of ore units, so it's 5496.238 m3 of ore, if mining veld, less if mining other ore. i think.

for reference, 5883.something m3 per cycle if you're using 2x5% implants.

then you can add drones.

the maths for the original scenario (3% implant, max skills, max boost, hulk pilot) is ~5.9 cans at just over 6m per jetcan of scordite, it's a ballpark figure of 36m per hour for high sec mining if you're cherry picking and doing absolutely everything you can to be as efficient as possible. i'd say if you're pulling in 30m/hr/miner then there's probably not much you can do to make more isk/hour other than moving to 0.0 grav sites. (and even then you'll have to be cherry picking)
