Since 1922, 38 decathlon world records have been set - 8 at the Olympics, with the last in 1984—but score comparisons over time are difficult due to multiple changes in the points tables.
The new Decathlon 2000 website is just amazing. I visit it every day, just for the fun and I find every day new informations. Simply the best website devotes to decathlon fans as I am - Daniel Urien
