What is considered a good SLG?

When it comes to evaluating the success of a cryptocurrency project, one key metric often considered is the 'Slugging Percentage' or SLG, though in the context of finance and crypto, it's more commonly referred to as a different metric altogether. However, if we're imagining a hypothetical scenario where SLG is indeed a relevant indicator, how would we define what constitutes a 'good' SLG? Is it a high number that signifies strong performance, or is it more nuanced than that? And how would we compare it across different projects or industries to get a true sense of its significance? As a cryptocurrency practitioner, I'm curious to understand the criteria that might be used to assess the quality of an SLG score.
