It appears that the diameters in the table are calculated by taking the sum of the two largest radii. Wouldn't it be better to take the sum of the NE+SW radii and the NW+SE radii and choosing the larger of the two?

This is how the table looks if you do that:
A table showing the largest Atlantic hurricanes by the size of the 34-knot wind diameter. The diameter was calculated by taking the sum of the NE+SW radii and the sum of the NW+SE radii and choosing the larger sum. Hurricane Klaus from the 1984 season leads with a diameter of 1,265 statute miles. Hurricane Faith from the 1966 season and Hurricane Lili from the 1996 season are tied for second with a diameter of 1,035 statute miles. In third place is Hurricane Sandy from the 2012 season with 1,000 miles. Hurricane Igor from 2010 and Hurricane Nicole from 2016 are tied in fourth with 865 miles. Next, in fifth place, is Hurricane Teddy from 2020 with 850 miles. In sixth place is Hurricane Earl from 2022 with 785 miles. In seventh place is Hurricane Karl from 2004 with 775 miles. In eighth place is Hurricane Florence from 2006 with 760 miles. In ninth place is Hurricane Helene from 2006 with 750 miles. Rounding out the top ten is the forecast for Hurricane Erin, valid at 11:00 AM Eastern Time on Wednesday, 20 August, with a forecast diameter of 715 miles. Hurricane Lorenzo from 2019 and Hurricane Epsilon from 2020 are tied for eleventh place with 700 miles. Next, in twelfth place is Hurricane Lee from 2023 with 690 miles. In thirteenth place is Hurricane Wilma from 2005 with 660 miles. And finishing the list, in fourteenth place, is Hurricane Sam from 2021 with a diameter of 655 miles.
