For me it's a bit relevant. I know it's calculated based on pp, thus your answer will wildly vary.
Personally, it's a guesstimate on my present capability. It sits at 5.61 currently, and I can naturally FC on that range, assuming typical and non-marathon maps.
It's way off with mods though. EZ is just impossible on mid 5* currently, both HR and DT separately is still too hard, at least for achieving same my acc standard (for mastery) at 99% as NM.
