Most of the corner ones should be, but I don't know about midscreen.
At any rate, I think it'd be worth remaking the thread for organisation's sake, so go ahead if you want to. I'll go through the old thread again to pick out any useful combos or information later.
I reckon a note in the first post would be an easy way to tackle this problem. Like you said, it's all down to judgement so I think having a small write-up that talks about proration and how they affect specific parts of Lambda's combos might be more useful than omitting some combos from the thread. Sound good?
