Faster return eta should come at a price.
The fastest eta should be if you don't get roids, then the slowest eta if you capped 25%. Between those two you could choose, at launch, that you're going for a lower cap. return eta -1: 20% cap max, eta -2: 15%...
In case of team up, the lower percentage applies to your share.

There should be a cov op allowing to see the return eta

but tbh i'm not convinced allowing a 2nd attack a day is what's needed, i much prefer UN suggestions, a Casino or a stock market, more/better quests
