Diff is at 2791 now... indicating somewhere between your 10% and 15%.... try 13%, I think I read that somewhere as the "official" number.
Yup, the only thing broken in diff adjustment is its design. But otherwise it "works" as intended.
What is worse:
1) A possibility of a 51% attack OR:
2) CoinHunter being the POLICE of your entire economy??! (and earning 10% of all coins to himself!!)
LOL
