    This countdown is based entirely on the 13-part survey series focused on the Best P4P boxers from each decade, 1890s-2010s. So for any of you who participated, the final results here reflect the forum consensus from that Survey.

    Took nearly 4 years from the beginning to get to this point, but it's been a fun and enjoyable (and educational) journey for me.

    I hope you all enjoy! Would love to hear your feedback (both here, and in the video comments as well).

    Cheers! :beer-toast1:

    @Rumsfeld you should consider doing a bump in a couple of weeks/months that has the written list in it.

    I don't get how Era Points% and Era Peak Multiplier are being calculated. Can you provide mathemathics for that?

    Crackin' job as always!

    @Rumsfeld I really enjoyed these results. Also, I want to commend you on a fine job of finding a wide variety of different adjectives to describe these great fighters. I know that is not an easy task.

    As for the list itself, I have always been a believer that greatness is measured by how great you are within your era because everything else is just speculation. I think this survey and your mathematical formula did a great job of bearing that out. I know the results are mathematically based, but I do believe it’s clear that the key element is longevity. Your formula did a great job of pointing out who is great and an even better job of pointing out how long they were great.

    This seems like a labor of love for you and I really appreciate the hard work you put into this just to entertain and inform a motley group of boxing fans.

    I'll do you one better, at some point I'll release the entire Top 203 (which is all I sorted through, because that's how many boxers finished inside the Top 20 across the 13 decades, where 57 boxers twice cracked the Top 20). Before that, though, I have more I'd like to try with the data. I wanted to do a Top 200 so badly, but that would have taken more than twice as long, and it may have realistically taken me until next year to complete.

    Thanks George. I was actually thinking of you when I scripted Ezzard's entry. :thumbsup:

    Thanks Maccaveli! Glad you liked it! The Era Points% is simply the share of total available ranking points a fighter took in his decade's survey. For example, in the 1980s the most points a boxer could receive was 4,750 (125 points x 38 volunteers). If we look at Aaron Pryor, who finished #10 in the 1980s, he acquired 1,519 points. So 1,519 / 4,750 = 31.978947368% Era Points%. On the graphics, that would be written as 32.0.

    The Peak Multiplier applied a smooth square-root curve based on where they finished (1st place getting King Tier, Top 5 getting Elite bonuses) to properly reward peak dominance without completely breaking the scale. Since Pryor finished in 10th place, his multiplier = 1 + (1 / sqrt(10)). (If he had finished 9th, that would be 1 + (1 / sqrt(9))).

    In the case of Pryor, his multiplier = 1.3162277660. Multiply his multiplier by his full (unrounded) Era Score%, and Pryor has a final score of 42.09157845. That reads as 42.09 for his final card on the graphic.

    Really appreciate the kind words and thoughtful breakdown, Fogger! You hit the nail on the head - greatness within your own era was the foundational metric here, and longevity across decades was what separated the all-time elite from the pack. Definitely a labor of love, and I'm thrilled you enjoyed the final product. I hope all the volunteers and the rest of the Classic section enjoy it as well!

    Certainly, the longevity factor plays into the, somewhat lower than some might expect, final ranking for Sugar Ray Leonard. No one can argue that he had a fantastic group of top wins over other all-time greats by but his career was only 12 years long and that included non-active gaps of two years and almost three years. This, of course, does not count his two end-of-career ill-advised comebacks.
