Accurate? Hardly. Skill is a subjective thing, best measured relative to others. If I went completely based on mario-man's little chart, I'd be a Very-n00b-average-exp-good player, because, guess what, not everybody develops their game in a linear fashion the way he laid it out. Besides that, there's no point in rating yourself on an eight-point scale because what really matters is how many people are better than you in your area.
