Cross-post from this thread. Will post actual opinion when I wake up tomorrow, this one's for the calculations.
My total net-worth in Dominion was 4 chaos and 2 stacks of alts plus a couple of miscellaneous orbs, at the time I lent them to a friend. In addition, I had bought about 4 stacks of transmutes (1alc per stack), leveling weapons (3chaos + 2chaos), Sunblast (8chaos), Karui Ward (1chaos) and Deerstalker (1chaos). Total of about 23 chaos. Two characters, level 47 and level 30. Can't use /played because there's a lot of dead-time where I AFK for lunch or just chat, but you can draw your own conclusions from the character levels. Ratios are assumed to be 20 alts to a chaos, 20 chromatics to a chaos, and everything following from it. I sold no items but I did freely convert currency in trade chat.
This is including picking up every blue item so I can id and vendor it - the average return, buying 160 ids to 1 chaos, is that I end up with about double the amount of currency I bought the id scrolls with when I run out of scrolls. I make close to zero if I don't pick blues, simply because rares and orbs drop so rarely. With a Perandus ring and no significant MF, I don't need to buy id scrolls even when picking up blues.
I can only do back-of-envelope calculations, but bear with me here. Clearing normal difficulty is about 3 hours on a fresh start (check the most recent 3 hour race). We'll say my level 30 cleared normal difficulty, since he pretty much did, so 3 hours there.
I'll now take some numbers from someone else's thread: level 65 in 10 hours at the highest clearspeed with a leveling build and all best gear available. I have used said leveling build, as well as others, and I can reasonably say the normal difficulty clear time is 2 hours, give or take 0.5. On the level 47 character, for all intents and purposes I started using a leveling build at level 28 (Geofri's Baptism) and have cleared the entirety of cruel with it. More or less. That's 3 hours, plus we'll just say half the time between a1c and a2m, so 4 hours. Would have been longer if I'd leveled with my final build.
So that comes out to about 3 chaos per hour, rounded up, playing solo self-found without MF gear and identifying every item. I'm not including the time taken going over vendors for chromatics, or going back to town to sell items, which are both fairly significant time sinks. It's likely to work out more around 2 chaos per playing hour.
I can make the figures per hour mentioned by someone else (80 alts, plus a few chaos from recipe, plus drops, adds up to about 8 chaos per hour) if I run a high-clearspeed MF build in endgame Piety/Dominus or maps. Goes through id scrolls at a fantastic rate too.
Thus, 2-8 chaos per hour without trading. There is an alternative - buy a pair of Perandus Signets and sell id scrolls for 200 to the chaos - I'll probably test it some other time, but this method is severely curtailed if you also want to find usable blue items. Blue items are really significant when you don't have much else. And, y'know, it kind of assumes trading.
