User blog comment:TravelBitten/Testing the "Double Your Money" Crystal Alchemy Store/@comment-5200570-20120921034705

I also choose not to let this game completely ruin my life, but I do have two of these stores. I never bought them intending to double my crystals, but I did get them hoping to make at least a 100 crystal profit on each store, along with the 30 (I think it was) crystal bonus for getting two stores, I'm hoping to net about 250 crystal profit. I'm not keeping track in the slightest, but my basic strategy is to look at the clock when it's time to start a new recipe.

If I am sure I'll be able to harvest in 9 - 11 hours I'll do the one crystal recipie, if it's anything over 11 hours I'll do the 2 crystal 20 hour recipie. My basic thought behind it is it's going to take 18 hours to do two individual 1 crystal recipies, which is a two hour difference between the 1 and 2 crystal recipie, so I add the 2 hour difference between recipies to get my 9 - 11 hour window. So often if it's the morning I'll run the 9 hour recipie, and anything mid-late afternoon I'll run the 20 hour recipie, if it's just before bed, the 1 crystal recipie.

I'm sure I could have said that in many less words, but you all get the point :)
