He gave a range, he did not specify a 200" every year, yes, true 200" are quite rare. However, his range is very reasonable in my experience. Even in our down years there are at least a couple/few over 160" to consider and in our up years...well, we once had pics/sightings of 9 different bucks that were 155"+, with a couple of those right at, or north of, 190".
Not all of those spent the majority of their time on us, but we wouldn't have their pic(s) if they didn't come on our place some. The biggest "problem" in those times...you start seeing A LOT of broken racks...just too many brutes around for there not to be some breakage going on.
FWIW, I know of other neighborhoods that are even stronger than that year in and year out.
