Those values are estimates, but here, let me do a breakdown:
Hyperion with 8x Modulated Deep Core Miner II's fitted with t2 crystals, 3x mining laser upgrade II's and 3x Co-proc II's.
Each laser pulls 379.846 m3 per 180s cycle. Without a Mining Foreman in group (which can be trained on the miners pilot and results in a 10% increase in yield) or even a mining director in group (which I have and is useful in groups of 3 or more), your looking at 1012.8 m3/min.
So I was actually giving a conservative estimate. Here, retriever, hulk, and brutix now:
2x Modulated Strip Miner II's with t2 crystals, Mining laser upgrade II and a Co-proc II
Each strip pulls 1188.63 m3 per 180s cycle, for a total of 792 m3/min.
Hulk (because once your in a covetor, your basically in a hulk):
3x Modulated Strip Miner II's with t2 crystals 2x Mining laser upgrade II's (if you don't have mining upgrades 5 you might only be able to fit 1, but there seems to be a lot of CPU left over)
Each strip pulls 1435.274 m3 per 180s cycle, for a total of 1435.274 m3/min (for the interested, thats filling a can every 18min!)
7x Modulated Deep Core Miner II w/t2 crystals, 4x co-proc II's and 1 Mining Laser Upgrade II (It should be pointed out that with 3 co-proc's and 2 mining laser upgrades, you exceed your CPU limit by less then a single tf! a single rig will make 2x mining laser upgrades fittable)
Each laser pulls 361.758 m3 per 180s cycle, for a total of 844.1 m3/min. Note that a brutix, being a BC, can drop a laser and fit a link to provide up to a 25% bonus to yield (10% for mining foreman 5, 10% mining director 5 + an additional 5% for warfare link specialist 5), making it more useful in groups of miners.
So my estimates where actually conservative. Sorry for the lengthy post, I just want to point out that its possible to be a pretty solid miner without ever training a barge skill, and especially if you want to be a group miner (like me). This is useful as it also cross trains you for some combat skills (as you have more room for drones now and such, and are more tempted when confronted with pirates to run back to base and refit for combat).
Obviously the Hulk is the best miner in game, I'm not disputing that, but I am saying that as EvE is a social game, and say, 4 people want to mine together, 4 Hulks is less mining efficient then 3 Hulks + 1 Brutix with a mining link. Mining should be done socially, not solo. So go kill a macro-miner in your area today!
Note: THE BRUTIX OUTMINES THE RETRIEVER!
