You'd need to measure before its under load, then put it at max load (30A) to see the maximum drop.
As Nunya said, if it's too late, don't sweat it.
BTW Nunya, I see a lot of people talk about their 10/4 SO extension cord on 30A receptacles. Aren't 10/4 SO's rated for 25A? What's the dealio?
I'm more curious than anything else. I think the 10 gauge between the inlet and the panel is fine... and I'm not going through the hassle of ripping that out and going with bigger gauge. But as long as it's not a ridiculous amount, nunya is right, it makes sense to go with 8 gauge for the longer cord I need from generator to inlet. If I wasn't making up a new one, I wouldn't spend the money, but since I need a longer length anyway, why not..
