How does Chess.com matchmaking work?

Just curious what Chess.com factors in with their rating-based matchmaking sys.

Are you matched with people from your same league level?

Are your other ELOs factored? (bullet ELO lightly factored in rapid?)

Is your W/L ratio factored?

Is there anything else that goes into it?

Leagues have no impact on pairings.

Rating is the primary mechanism, for the pool you're playing in, and the site tries not to pair members with low and high lag together. There's also a sportsmanship pool, where players that have a high disconnect/abort rate are paired together.

Number of games or win/loss rate has no impact

Is Rating Deviation plays a role too?

Not to my knowledge.
