If you are going to test your strength with a 1RM you would want to know what you're doing.
I personally don't see the need if one is progressing on their normal template
If your progressing on normal workout yeah your right you don't have to max but is still a way of getting stronger.
I think a lot of the issue here is some people don't like being called beginners but really I have deadlifted 270 a few times now and I still see myself as pretty much a beginner lifter. I feel I have a long way to go before being advanced.
