Yes. That's most optimal. It yields highest light per minute and grows fastest as each convergence gives boost to light production, so it grows arithmetically. Seems slow but it does add up, each cycle has higher light/m.
The problem is that you need to have the game visible, at least in firefox. Can't change tab, nor even scroll to comments lol, it seems that simulation stops if you're not looking at it, so it's a bit of PIA to get it.
