To recoup that cost yes, but what is the break even point for dev points accumulated? You get the 21% increase right away with the trainer and a sliding scale as you increase your endurance over the ~year. Sure if you have the 15 mil up front go for it.

If you give me your data (pm if you want) on energy trained and cash spent on trainer for a month I could try to figure out the best use of cash.
