Introduction and Methods:
I noticed previously that tier 8 matchmaking was awful and I wanted to look at matchmaking in general. I recoded data about my solo pub battles since patch 1.01 in an Excel spreadsheet. After I started recording the game data, I learned that the community contributors that were at Tankfest were told that the system to make you more likely to be middle or top tier after being bottom tier was not implemented.
I played 1,013 solo pub battles since the release of patch 1.01 until this week. For every battle, I recorded tank played, tank tier, battle tier, battle type(3/5/7, 5/10, or all the same tier), win/loss/draw, and other information. Most of the battles were played during 7 to 11 PM East coast time on the US Central server.
Out of those battles, 484 of them were tier 8 tanks. Of those tier 8 battles, 52 of tier 8 battles were pref matchmaking tier 8 tanks.
