    The metric you are looking for is called Accumulated Cyclonic Energy (ACE).

     Basically  ACE is a measure of the kinetic energy of a storms winds multiplied by the length of time it had those winds. This is computed as the integral of the square of maximum sustained wind velocity with time over the duration of each storms life and added up over the hurricane season. 

    In other words- ACE takes into account the lifespan of storms and not simply the duration. It weighs heavily towards seasons with more long tracking Cape Verde type storms ( those forming from African tropical waves in the Atlantic)  rather than seasons with a large storm count or even a large major hurricane count. 2017 is an example, it produced "only" 17 named storms (compared to 30 this year) but exceeded 2020 in ACE because many of its strongest major hurricanes were  long tracking storms  (ie Irma and Maria).  The set up just wasn't as good for producing majors in the Atlantic this September. But the season overproduced in the Caribbean in October and November. However, those storms (and Laura in August ) had a limited duration of time as major hurricanes due to their location and this resulted in less contribution to ACE. 

    This year's ACE was in the 170s. This is considered "extremely active" when compared to 1981-2010 averages, but is not top 10.

    There was only 1 Category 5 hurricane. In 2005 there were 3, Katrina, Rita and Wilma. That is?still a record.
