The problem with who ever made this analysis is that he probably used faucets that give you less than 500 satoshis, which are in fact not worth your time, since there's faucets there paying you over 1000 satoshis. If you spend hours running faucets to get 200 satoshis again and again and again you won't make any profit, you will just end up wasting time. In my opinion, the best way to use faucets is to go on a list/rotator and run the highest paying first, makejar.com for example, has about 20~30 faucets paying 1000 satoshis or more, so in a few minutes you will get at least 20k satoshis, then you will face the reward decreasing (bc this faucets normally has long timers): 900>800>500... once you get to the ones that pay less than 500 satoshis, you stop and do something else or keep running the 500~700 satoshis faucets that will show up every hour and meanwhile you use the low paying ones (200~300), that's when it starts to get boring, but when you start to do that you will already have made over 50k satoshis, you can do that until you reach your threshold, i normally make 100k satoshis in a few hours everyday just to buy hashpower on ZeusHash.com.
