Premier rating
Premier uses a numerical CS Rating and a map-veto format. A quote should use the precise starting and target rating band rather than translating it into an unrelated Competitive rank.
FACEIT level
FACEIT has its own level and Elo system, separate from Valve matchmaking. Region, anti-cheat access and party eligibility matter, so they should be confirmed before scheduling.
Competitive map rank
Competitive ranks are tracked per map. Name the map in the order: a Mirage rank does not describe the account's Inferno rank.
Wingman
Wingman is a separate two-player ladder. Its shorter matches and different map pool mean a Competitive or Premier estimate should not simply be reused.
