How come, OT? I would have said it was "discharge when you really need it, because you're gaining a lot every turn..."
Because Excel told me so. (I am double checking the equation now since it is a counter intuitive result)
2(x-1)-3 is the quanta gained when this is discharged x turns after the first discharge.
N is the number of turns in the game
( 2(x-1)-3 ) x (N/x) is the total quanta produced
Nvm. I had an extra 1/x in the equation. The Mormegil is right. Discharging it at the last moment, despite being less funny, is more optimal by far.
