Well no, what I said was, a decade ago was the most active period for Hurricanes. This current decade is less active than the previous one, or the 1930's or the 1960's. Most decades have little to no Cat 5 hurricane activity so if you take the last 2 decades and compare them to the previous 10, then Hurricane density seems 3 times higher even though it is currently lower than it was 70 or 100 years ago depending on your measurement period. If we were to bin in 20 year chunks, then it would put this bin as the most active by a small margin. The most reasonable way to organize it would probably be year by year but category 5's are a relatively rare event so you don't see much variation if you just compare individual years. Most are 0, with high points being 2 a year, and a very rare 3 in a year. The real issue is that extreme hurricanes are clustered events. There seem to be a number of years where they hit heavily, then stop for a while before starting back up and we only have about 100 years worth of records which isn't enough to make a lot of meaningful predictions for something that seems to run on a 30 to 40 year cycle.
This is without touching on the issue of measurement bias, which is extremely difficult to determine the level of.
