You have to realize that what you're saying is true of groundwave, but not of skywave. Yes, a low end frequency like 550 can make 5 kw sound like 50 kw given decent ground conductivity. Great example here in the midwest: 550 KTRS (5 kw) versus 1120 KMOX (50 kw). During the day, KTRS gets out almost as far as KMOX with 1/10 of the power. However, at night, KMOX makes the east coast without any trouble at all via skywave, KTRS is enhanced a bit in N. Illinois - but it's NOT heard in VA or PA.
This is why I'm in the position of skeptical buzzkiller here. I don't believe that KUZZ was audible in VA with 5 kw on 550 when there are so many other possibilities. If anything, you have a harder time getting that distant skip on 550 than you would with something like 1070 or (even better) 1520 - with all things equal. Which they are not.
