Gladiator himself certainly has NEVER had a feat like that in all of 616, so even if we ignore everything else and considering it a 616 feat I'd still call it an outlier for him.
Gladiator, compared to characters with things like actual ongoing series or even just on the B-list of characters, barely exists in comics, and of those times he shows up, the times where he actually does anything of note are further fractional to that. It's not like he has an actual big ol career to go "but years and years of Gladiator performances..." The feat stands in fine with a guy who has otherwise had a fight measured in nanoseconds, blitz charged a guy across a galaxy in an eyeblink, outrace photons and on a minor note, apparently count to ten billion within moments. As far as board standards, it sits in fine thereby with both viable high end performances and presentation.
