We're exactly 50% of the way from August 13th to October 22nd
Theory: October 22nd is in exactly 5 weeks, the most likely release date for October 2023. In the 10th anniversary video the "days since 2.1" glitches out at 2470 days, which is (16.01.2017 + 2470 days = 22.10.2023). 22 / 10 = 2.2 and GD started in 1.0 (10 without dot).
