If you wanna extrapolate you gotta look at the numbers more carefully. After every release there's been period before the percentages start moving. It only really starts around the public release, whether that's because Cari is taking a break or because he's doing preparatory work (sketching on future plot points, commissioning artwork) before really starting working on the next update.Dude you gotta go back to school learn arithmetics.
Last update's been released in march 21. I.e. it's been 120 days now, with 44% reportedly done, or 11%/month. So if dev progress still follows this speed (and we all know the last 10% always last a lot more), update will come at the very earliest by Jan 2025.
He started working on this update mid-april and it's been pretty consistently 0.5% per day. We should be right around 50% done now, meaning it's around 100 days until the next release (probably plus/minus 20 days because I doubt the percentages are that accurate). This does indeed put the next update at late october/early november.
