in terms of the most severe extreme tornado damage that wasn't rated EF5/F5 it would be
Bakersfield Valley F4 June 1990 (should be rated F5)
Marion County - Barnes F4+ July 2004 (should be rated F5)
Barnesville EF3+ April 2011 (should be rated EF5)
Cordova EF4 April 2011
Cullman EF4 April 2011
Holly Springs-Ashland EF4 Dec 2015
Chapman EF4+ May 2016
Monette EF4 Dec 2021
Mayfield - Bremen EF4 Dec 2021 (should be rated EF5)
i wonder if there is some new info for barnsville , bakersfield? almost no info on them.
the 4 i listed as should be rated EF5/F5 is for a reason , i am developing (still in construction) a way to compare all the most violent tornado in a unbias way , the biggest problem is i am unable to get rid of the 4 from the EF5 wind speed range , if i force it almost all 2007-2013 EF5 get kick down to EF4 rank.
(extra note , i couldn't get Greensburg in the EF5 group for a while without having 11+ EF4 going EF5 , but new info from this year was able to fix that)
i kept hearing how this past tornado wouldn't be rated EF5 today , so i decided to make this project , its interesting to note how 80% of all F5 wouldnt be rated EF5 it seems.
i hope i can get some input about it once it reaches version 0.9 (its at 0.2 right now).
only other thing to say is for now Smithville EF5 seems to be on top... by a lot.
