To me a proper push-up is nose to the ground. That is what is used for testing in militaries etc.

Military uses arms at a 90 degree level.

When I took basic in the Army you had to hit the ground(floor)with your chest or it didn’t count. And you had to count them out loud, if you failed to go all the way down the DI disallowed that one. Back in the day I could do 100 push ups, I believe the record for push ups is somewhere in the thousands.
