That is a fair question, and was a concern with the first ELO formulation, but I haven’t seen a glicko-2 formulation with a singular entry point (1500) that was deflated (OK OGS but that’s because of the rating-rank conversion). Lichess being the primary example is considered a very inflated server in chess where 1500 is actually quite easy to reach, especially in comparison to Over the Board ratings, where there is a history of complaining about inflationary mechanics (such as never being able to fall below a certain floor once you’ve achieved a certain rating). But an eye to that and readjustment of what the ranks are is definitely worth something
