On the snatch - all they are looking for is the lock out at the top which is fine. I suppose this is only way to make sure people lock out and that as a judge can clearly see it. As for eye level or below.... BRO REPS
The burpee - i have the same opinion as Vic. You can actually jump with your feet offset but still at the same time. This is not clearly stated they need to be parallel at all.
I was checking a few different sites and none of them have the same clear view on the burpee. Some say you have to lock out/stand up at the top and some don't.
This needs to be sorted out and in writing on the CF homepage.
