Don't try to fake an injury. It'll just make you look bad.
For instance, when I told you I'm going to measure your knee, you only bent it 80 degrees. When I put you on a bike, what you don't know and I do is that it takes 100-105 degrees to bike in full revolutions, and that's if the bike is properly adjusted. So if it's too close, and you can still bike in full revolutions, that is what we call an inconsistency. We can't call it a lie, because we can't feel for sure where your pain is or how bad it is, but it is definitely an inconsistency.
When I was
young and dumb less experienced and more naive, I had a lot harder time telling the difference between normal variations in injuries and certain inconsistencies. Now I can't always prove it, but I can usually tell if:
You are really injured, but are milking it a little bit.
You are really injured, but are just a big baby about pain (12/10 on a pain scale is a big hint).
You are really injured, and you're actually hurting more than you want to tell me.
You are really injured, but the pain is referred from something else.
You are not really injured.
In a situation like this, it's usually a combo of the first two. There were enough things in your case to make me seriously consider the last one. I don't think I've ever seriously considered the last option. Really. Don't try to fake it. You're no good at it.
