The Rosetta challenge starts on the 27th at 0800 UTC. The WU have a 8 day deadline so you can bet your bottom dollar Italy has been bunkering big time.

I ran a Rosetta challenge in early Oct and found a trick on it. If you bunker you have no choice but to load up with long running WU so you get enough. When it goes live you want to set it for 1 hour WU, kill your cache, and then set it for .01/.01.

The project releases new WU strains quite regularly. Until it gets enough back to know how long they take it pays 5-10X normal credits for them - kinda like credit screw. Once enough of each type is returned then it knows what they should be and reduces the credits accordingly. If you have a very very small cache you'll get these while they are paying higher than normal. If you have a big cache then by the time you get around to crunching them the project will have already reduced the payout. You'll get 50-75% more daily credits if you do this
