You know you can do all that with Pyfa, right? So you can actually get solid ‘what’s the max possible yield on this ship?’ numbers for every mining platform in the game, Gnosis included.
Which is why I can tell you, without any difficulty at all, that no, your mining Gnosis, with it’s theoretical max yield of 21.6m3/s of yield, using 5 augmented mining drones and 5 civilian miners, is neither equivalent, nor exceeds, the 58.2m3/s a max-yield Hulk can produce with Orca boosts. Without boosts, the Hulk’s 37.2m3/s is still superior to the Gnosis.
So, let’s break down max possible yields on the mining platforms, leaving off the yields the boosters get, because we’re not stupid, and we’re gonna keep those boosters right where they need to be (no attempting half-assed boosts from a Gnosis, for example). We’re going to avoid faction modules to keep things from getting ridiculously unbalanced. We’re also not going to worry about drone speed modules or implants, and assume (as pyfa does) 0m travel time needed on the drones:
Exhumers:
Hulk: 58.2m3/s [65.1m3/s ICE]
Mackinaw: 45.1m3/s [47.9m3/s ICE]
Skiff: 45.1m3/s [47.9m3/s ICE]
Barges:
Covetor: 51.3m3/s [55.3m3/s ICE]
Retriever: 40.3m3/s [37.5m3/s ICE]
Procurer: 39.5m3/s [34.1m3/s ICE]
Expedition Frigates:
Prospect: 23.1m3/s [19.8m3/s ICE]
Endurance: 16.9m3/s [47.9m3/s ICE, which is what this 1-turret slot wonder’s designed to mine.]
Mining Frigate:
Venture: 16.8m3/s [0m3/s ICE]
Mining Titan/Battleship: (just some examples)
Avatar (6 turrets, 8 lows, no drones): 28.8m3/s [0m3/s ICE]
Praxis (6 turrets, 7 lows, 100mbit drone capacity. Also a 1% CPU implant to fudge it just a little): 34.7m3/s [16.3m3/s ICE]
Gnosis: 21.6m3/s [8.14m3/s ICE]
As you can see, the Gnosis doesn’t come close to the exhumers. Even the barges leave it behind.
And there’s more than one titan out there with civilian miners and/or miner IIs out there. As for this…
No. Don’t do that. Use an AB. If hostiles come into system and you have to bail, turning off the AB is just as fast as turning off the MWD. If you get distracted and only spot them on warp-in, the AB doesn’t bloom you up to cruiser-size on the SIG, so you have critical moments longer before they can lock you. Even if they do, your defense is not speed (because they’ll have something that can do more than the 3700m/s you can), but evasion: small signature to minimize incoming damage. The MWD’s not going to a damned thing once you’re scrammed and webbed, but an AB will still help, just a little. Who knows, you might live long enough for someone to kill the guy tackling you. You won’t with an MWD.
The Thalia and Scalpel can get to a ridiculously small sig radius. You put MWDs on them to keep up with other MWD frigates, but you definitely don’t want them MWDing in an orbit around an immobile rock.
As for the drones from a ‘swam fleet’ of frigate miners? Yeah, I see a bunch of guys in a system where I’m hunting, I’m getting cloaky eyes on them, first. They’re frigates? 1 guy’s bringing a couple of smartbombs, or a few of us will each fit 1 SB, and poof, you have no drones.
If you want to be safe while you’re mining, your best bet remains more people. Not more dudes in tiny little specialty frigates wasting their bonuses by fitting mining lasers, though. Scouts, sitting cloaked on the gates of the system. A few combat pilots in combat-ready ships, sitting overwatch. Falcons or Blackbirds, a good 100-120km off to jam tackle and run once the miners are clear, would be my advice. And then you use absolutely the best balance of tank, GTFO, and mining yield you can get. This is normally going to be a Skiff, if you’ve got a booster who can carry the ore. Then you really just need to worry about keeping that booster alive.
