I wonder how much power is required to keep the window open larger, and how much power is required to keep them open longer - because actually, I would be inclined to believe that early subspace-capable would have been made with energy efficiency most in mind, because of the uncertainty of the experiment and greater costs involved. But I could be wrong.
I was wondering the same thing for a story I was writing... (Non-FS but had similar tech.) Personally, I think it might be something like: e=a^2*t
e - Energy required to complete jump
a - Total area of circular jump hole
t - Duration of jump in seconds
Thus longer would be more efficient... But I'm sure someone else has a differing view...
[edit] I just realized the letters I chose for my formula spell the word "eat"...

How ironic!
