Well fuck me, that's good timing... That puts the new projection to 11/23 and total progress to 59.5%.
Couple of things could be going on here, these just spring to mind immediately:
1) He's got a kick in the backside from Patreons and is actually putting in a full day of work because it's been made clear that another 5-month cycle will have financial consequences.
2) It's the same as above, except he's always been able to work this fast and has deliberately been sitting on progress and updates to extend the development cycle, and therefore increase his total income over the lifespan of the game. (The short word for this is "Milking")
3) He's just losing interest in a lot of the peripheral elements of the stories and he's cutting material.
My guess, #3.
