Beginner, Intermediate or Advanced weights?

This is 100% subjective, but assuming your gym was split up into three classes of weight lifters; Beginners, intermediates and advanced. What class would you put someone in, based entirely on how much they could DB Bench Press, BB Bench Press, Dead-lift and Squat with correct form 6-8x3.

For example, my personal opinion would be;

DB Bench Press (Kg per DB)  = Beginner less than 30 | Intermediate 30-40 | Advanced 41+
BB Bench Press (Kg) = Beginner less than 60 | Intermediate 60-100 | Advanced 101+
Dead-lift (Kg) = Beginner less than 100 | Intermediate 100-... etc
Squat (Kg) = etc

What do you guys think?

As you say it's a grey area. I assume we are talking about pbs here? Plus bodyweight and what you train for are gona affect things. For instance you may bench 120kg but if your 6'52 and 120kg then you may have done that after a couple of months. However a 67.5kg powerlifter doing that at a meet may be quite an advanced lifter.

A guy that dose other sport etc etc may be happy with a 100kg bench even though they are very experinced in a whole range of lifting.

Anyway given all that and the fact that pure weight lifted is often not an indicator of knowledge and experince;

Squat (to depth)- <100 = begginer, 140-180 = intermidiate, +200 advanced

Deadlift- <140, 200, 250.

Bench- 80, 120, 150

Also depends what kinda of gym you train in; for a normal fitness center, 100kg bench might be advanced... for a powerlifting gym, it's a joke for all but the lightest men and females

Yep, context is everything.
