I just look for absolutely terrible, can't do it at all, minor flaw, or pretty close to good. That's really all I'm looking for. So my scoring system is zero, one, three. Zero is like, you're not going to do this exercise because you're at a very high acute risk. You might get hurt on rep one tomorrow. Number one, a score of one is like, there's a minor flaw here. We can probably do it, but we need to be cautious of load and volume. And the other one is, maybe it's perfect, maybe it's not, but go ahead and it on a reasonable protocol. You'll be fine.
