I know everyone has an idea in their head where they draw the line on minimum defensive rounds but I think the line between 38 and 380 is cobweb thin. That line would be better drawn between 380 and 32 or between 38 and 38+P. Yes, I said it, I think there's a bigger energy gap between 38+P and 38 than there is between 38 and 380.
