Yeah, it'd be nice to have something like that but it gets totally misinterpreted so he regrets the way he presented it.
My understanding is that the various designations refer solely to an individual's (likely!) current place in their own person training history for a given lift, rather than some objective, Platonic standard. So when the chart tells you are 'Intermediate' that suggests that you are somewhere in the middle of your ability to train that lift, not that you are 'intermediate' in relation to the wider class of all humans who've done that lift.
That leads to some uncomfortable nuances - if you are 'Advanced', what he is actually saying is that you are close to maxed out on the lift, rather than being just awesomely strong or something. It is of course awesome for anyone to approach maxing themselves out on any lift of course; that should go without saying...
It can still be useful for motivational purposes obviously, but take it in the spirit he presents it.
