Well if he is spending 12 hours and only getting 0.005 he is doing something wrong because you could get that amount even from only faucet farming, 12 hours is a lot.
0.005 from faucets only in a day? I'm not really interested in spending my time on faucets, but I'm curious as to how one day of faucet work would even get 0.005 bitcoin?
Well you have to have lightning fingers, a facuets usually pays 1000-2000 satoshi hourly, and it takes 5-10 seconds to solve a captcha, so you can complete 514 faucets in an hour if you work nonstop. Thats 0.01 BTC/hour.
So in 8 hour of work, you can earn 0.08 BTC easily
Of course if your faucet list is big enough, check out this list for example and see what i`m talking about:
