My understanding of the cause of the change in this FA, "it is operating as intended", as in none of the increases were typos, and INNO really did mean to make the Sacks 4x harder, but "it wasn't intended to be implemented in this FA", which might mean they intended to roll it out first to the Beta server in the next FA, and then to us, possibly with official announcements to both.
I did say my numbers were my numbers. I recognize that I am in a Late Chapter, playing a large city (with many, but nowhere near all, Premium Expansions) and with a highly overscouted Map, and so my numbers and my situation are mine and not yours.
Also, I was looking at my per chapter numbers posted in another thread, and found I made a mistake in computing NH effects. So, some of my rosier predictions are lessened.
Look, I'm not happy with this change. I liked the fact that I could previously ignore Sack production, it was so automatically easy. I do think that 4x is a large increase and changes the balance of the game. But, I'm a math person. It may look dire looking at individual pieces of the Sack production puzzle. But, it's less so if you take into account all the different sources of Sack production. Yes, this came at us cold, so we haven't been able to prepare. And yes, the preparations seem small. But, they can add up. We're not used to trying to think about optimizing Coins production. It's a Lemonade from Lemons. It's adjusting expectations and priorities.
