short version:

More duration = longer stuffs.

Stuff that's endlessly draining energy drains less energy with more duration, but never less than 25%.

190% efficiency at 40% duration does that.

175% efficiency at 100% duration does that.

130% efficiency at 282% duration does that.

100% efficiency and ~400% duration would do that.

higher always also works - but you won't pay less than 25%.
