How do you differentiate from regular physicals to Force augment?

You can do it in the cases when they're specifically not using the Force.

Feats before they were trained to augment are largely their physical base stats.

Or if they're purposefully not using it, like I think Maul was a few times when he was hiding his sensitivity.

Or if they're cut off from their power, like Ulic vs Sylvar or Nox vs Paladius. In both cases they performed admirably against a force-user in melee even without the force. Indicating that they're near-superhuman already in just physicals and would be far superior with the Force.

See I was thinking that Neph, that all Force Users or at least the more combat oriented ones would be at minimum all Peak Human(at least until they get older and would need to rely on more The Force)...which makes sense according to the Jedi Path where they master and then push their bodies beyond normal limitations.

But then I thought that would be kinda strange.

Then I was thinking, in the SWU you have Enforcers, thugs within criminal organizations being able to lift at least 1 ton, Clones/Stormtroopers/Regular Troopers generally going through intense training to be Peak Humans.

So maybe looking at the Galaxy as a whole, it wouldn't be that strange since the JO is fairly small in the grand scheme of things...but I wasn't really sure. I mean I would guess that's fine, given the variety of alien species/hostile, where humans who are involved in combat(along with the different alien species), would need to achieve the highest level of physicals just to try and match them since a lot of species would outclass them physical wise...so I guess it's not that much of a stretch.
