Well, post away, i'm sure everyone thinking and bashing heads together could make sense of whatever you have to say, and something good could come out of it. Nothing good has ever come by withhelding ideas.
As for the whole turtles vs quarry thing... Using a BC3 Quarry, for me, is in no way different than going to the computercraft forums and downloading an efficient mining program for a turtle. I don't see any distinction. In both instances, you are placing a block, giving it a command, either in the form of a redstone signal or a command word, and providing it energy, either through the turtle GUI or through tesseracts/REC's, and it does the job for you, efficiently, and fast. The question, then, becomes one of efficiency. Which is the most efficient? According to AustinKK, his Advanced Ore Quarry program can compete in terms of speed with a full speed BC3 Quarry, beating it just barely. That was back when they had first upgraded the Quarry to accept up to 45 MJ/t, but at the time of the video, and according to his tests, there was no difference between giving the full 100MJ/t of a REC and giving it 25 MJ/t - I.E, it maxed out at about 25MJ/t.
Ignoring that, and accepting that a fully sped up BC3 quarry can now mine faster than his program, we have to consider the infrastructure. Even without Gregtech, you're talking about 11 diamonds per quarry. To actually feed it enough power to run at max speed, though, you have to have a pretty stable energy setup going on already. 45 MJ/t isn't something trivial. That's 5 and a half Industrial Steam Engines, which cost a lot of steel to make, or 7 and a half Combustion Engines running on Fuel. Either way, it's a hell of an infrastructure to set up before you get your first quarry going on. How to mine all those resources to get to peak efficiency?
I'd say using a turtle is, hands down, better than mining it by hand. Ok, then you get your first quarry online, and it's faster than a turtle... But to set up another Quarry at max speed, you again, need 45 MJ/t. It means even more infrastructure to setup. By the time you got to your second quarry, you used 22 diamonds. Those 22 diamonds could have made 7 Mining Turtles. My point? Mining with turtle scales better, and faster. After your first trip to Y12, you get your first turtle online, and you never have to manually mine a single block ever again. You make more turtles. And more turtles, and more turtles, until your sorting system can't keep up. A BC3 Quarry isn't as efficient as 3 turtles running advanced mining programs at once. And they cost equivalent amounts of resources, and you don't even need to use Diamonds for the turtles, either, you could easily just skip it entirely by using Green Sapphires, which are basically useless besides that and tools.
It's pretty easy to get at a point, with turtles, that you're getting such a silly amount of resources, that it's actually hard to know what to do with it all. Eventually you get to manage 20, 30 turtles at once, via Rednet or other means, and it's silly. The competitive solution, in my eyes, is only the Mining Well frame machine that DW20 came up with, which is lolwtf levels of broken and silly. 1 Block per Tick is insanity right there.
