Recently, the statistics website Leetify counted a total of 540 million rounds in the official matching match from July 20, 2021 to January 13, 2023, limited to service maps. On the map, the map most affected by the weakening of the M4A1 is Ancient.

CSGOM4A1 weakens the impact: CT win rate decreases significantly

The statistics website Leetify counted a total of 540 million rounds (yes, 540 million!) in official matchmaking matches from July 20, 2021 to January 13, 2023, limited to service maps. Finally, the impact of M4A1 on the change of win rate of different dan players on different maps as CT is calculated after several updates.

During this time period, the current M4A1 has recently undergone two updates. Between July 20, 2021 and September 20, 2021, the M4A1's firearms data was not so perverted. In particular, the body damage value is only 33.

On September 21, 2021, the M4A1 was significantly strengthened. The physical damage value was adjusted from 33 to 38, which also made the A4 party completely marginal. It wasn't until after last year's Rio Major that the M4A1 finally became what we see now: the distance attenuation of the M4A1 directly weakened the M4A1's mid- and long-range power. At the same time, the ammunition capacity was adjusted from 25 rounds to 20 rounds, which also allowed the A4 party to rise.

During the sample period from March 20, 2022 to May 20, 2022, factors that may affect CT win rate also include the weakening of the Sand Eagle, which can no longer kill enemies with two shots in the chest at close range.

In the sample period from November 18, 2022 to January 13, 2023, factors that may affect CT win rate include: Ancite fine-tuning; Dust2 being replaced by Anubis.

On the whole, after the weakening of A1, the CT win rate of players in various official ranks has decreased, but the decline is not consistent. From the perspective of rank, M4A1 weakening has the greatest impact on players in the middle rank. The lowest silver players don't actually have a particularly big impact. The decline from the gold segment to the chrysanthemum segment reached about 2.4%. The higher the dan rank, the smaller the decline, and to the big earth segment, the CT win rate decreased by only 0.8% after the A1 weakened.

On the map, the map most affected by the weakening of M4A1 is Ancient, which reached 3.2%. However, it is important to note that the Ancient map adjustment preceded the M4A1 weakening. In addition to Ancient, Nuke, Overpass and Vertigo's CT win rate decline has a greater impact. Conversely, the CT win rate of Mirage, Inferno and Dust2 had less impact.
