Would it be possible develop an alert from CM when we have hourly spikes in profitability? I ask because leasing a rig for extra hash power would make that lease instantly profitable.
For instance, today -June 3rd- CM had brief but enormous spikes in profitability:
http://www.clevermining.com/profits/24-hoursHour 13 231% profit over litecoin
Hour 14 301% profit over litecoin
If I had known these spikes were happening in almost real time, I could have leased a rig for an hour, and while I wouldn't have had the full % benefit, I would have made some extra
BTC. After the spike was gone / lease was up, I would continue hashing away with only my equipment, business as usual. Would this work or is it too volatile? Is the mining/trading of profitable coin only calculable after all transactions are complete?
Does this make sense to anyone else or am I dreaming about flying unicorns again?

Makes sense, but it's kind of like predicting the future; because AFAIK those stats are updated once the hour has ended. You could try and chance it by renting a rig after one hour of crazy profitability hoping it would carry forward, like it did from hours 13-14. Or chance it after a long period of abysmal profitability hoping it rebounds. Pretty much find a Unicorn and you'll be fine.
