I think I understand more or less. Thanks.
Maybe a little more specifics might help.
Match Play does not affect your average UNLESS you beat someone in Match Play that is in a higher tier than you are.
The specifics of exactly how much and for how long are a mystery so far as WGT will not disclose the math behind it.
When a player beats someone in match play in a hgher tier their average will drop. IF that dro is sufficient to put them i higher tier then they are place in the next highest tier.
For example as a Tour Pro I beat a Master when I was close becoming a Master anyway and I became a Master. A few days back playing as a Master I beat a Legend in Match Play. My average dropped but I still am a Master because I was nowhere near becoming a Tour Master.
The effects of that drop are fading however with time and stroke play rounds played
