It wouldn’t surprise me (do you know an era?).
Even “78s” could have an optimal playing speed anywhere from 70 to 80 depending on the company and era (pitch bending can help make things better).
I believe the EP format was from the 1950s, but I wasn’t yet born and don’t know the release date of the one my dad had. I don’t remember him ever playing it, at least not when I was in the house.
