Below is a link to the IC Database, which has, as of 10/5/2023, a catalog of every single match — all 4960 — in which the Intercontinental Championship was on the line, broken by reign and analyzed with the Kayfabemetrics formula.
I will be writing some pieces and I am currently working on some graphics to go along with the numbers, but I wanted you good folks to have a chance to look at the (mostly) raw numbers.
