Engine efficiency chart

[Aghanim]

I remember somewhere here in this forum there is a chart about engine thrust efficiency and rocket mass, like when LVN becomes more efficient than LV 309 for interplanetary space. Can someone point me to the right direction?

Ought to find the answer in there somewhere. The first is my favorite, though the other is good too. For interplanetary space you want the first image in the slideshow on the first link.
