with your formula you get negative drain for durations <100% and efficiency=200% and 0 drain for 100%efficiency and 50%duration, which also makes no sense.

with the current formula, you get 0 drain with 200% efficiency.

both are incorrect, as you will always just have 25% of the original drain value with 200% efficiency. you get the real ingame results if you use the formula on the page and just replace every result thats <25% base drain value by exactly 25% base drain value.

if someone could squish that into a single formula, i have no idea how to do that without a case differentiation.
