Just to be clear we are talking about waiting for an additional aetherflow stack before summoning demi in order to push the waves right? If so I find it odd that the get max power we need 3 stacks of aether and not just the initial cost of 2 even though I don't argue the testing and math behind it. If anything that itself feels clunky. If we have the power to summon demi after 2 stacks we should be able to use the summon to its full ability at the 2 stack mark. If I am wrong in what you are inferring I would very much like someone to correct me though!
