The OP is nerfing his cargo with a scoop as well as a DC. have some pride in yourself, push your comfort zone and learn to dock. Store that scoop at the cg you don't need it to get the Lithium. I'm at work on a laptop using mouse and keyboard and doing a few runs in the Cutter. I use HOTAS at home and M+KB is awkward but I'm getting the hang of it and with no DC eating into my profits.
Hey genius, did you miss the part where I said I know how to dock, that I've docked thousands of times manually? Or the part about reversing through the mail slot, with rotation correction turned off? I can't help but to laugh a bit here. I don't use the DC on my Type-9 because it's even remotely challenging to dock it - I do it so I can do other things, like plot my return trip while the computer is bringing it in for me. It just saves me some time. Sure, I could strip the DC, the Fuel Scoop, the Shield Generator and the Fighter bay and go nothing but cargo racks like everyone else - but why "Play Everyone Else's Way" when I can "Play My Own Way" and enjoy my game?
I don't have to give a rat's biowaste outlet about my profits - I'm an Elite Trader. My rank isn't going to get any higher. I own a fleet of 37 ships, including 2 Beluga, an Anaconda, a Cutter and a Corvette, all fully upgraded, fully engineered, and I'm banking more than enough to cover the rebuy cost of any of my ships....
Seriously does it look like I have to pinch my pennies? I don't have to do anything, I've already done it. I can honestly sit back and play purely for fun - no worrying about Cr/H. So I try to find ways to do things more efficiently, and this is one of them.
At least it is for me. If someone else tries it and it helps them out, great. If someone else tries it and it doesn't make any difference, then what are they out? Especially since modules resell at full price - yep, nothing at all.
I do CG's typically because I just want to make some extra credits - maybe buy myself a second vulture, or another Adder, or an extra module of some sort. With the setup I run, I can typically park myself in the top 25% within an hour, top 10% in an hour and a half. I don't feel the need to be in the top 10 commanders.
I only use a HOTAS, I wouldn't game on a laptop, I don't like it. And I don't get to game at work, because, well, I'm there to work.
