I love SoggyShorts analysis.
It makes sense.. lower chapters, a lot more Tier I.. by halflings, you'll need more Tier III but you can substantially lower the amount of Tier I manufactories.
You will however need to take into account variables like your FS and you hood/ trader and your boosted - and their level..
and whether you fight or cater, and to what degree.
I've a radical suggestion.. don't aim for an even spread across Tier's or even a rebalancing of goods - when you get seriously high on one and very low on another.. build and trade according to need.
I have 3 related goods.. steel, scrolls and dust - in an area (Hood and FS) where no one needs steel or dust, but scrolls are always in short supply.. sounds great right? I can anticipate and always sell my scrolls.. but sometimes I have such a surplus of crystal that I either have to sit on it for weeks.. or avoid buying when I really want to..
I've been vocal on other threads about back cross tier trading.. I could seriously discount the crystal for planks/ marble or even my own boosted.. steel.. Well. I do and I have done.. but of course, I am then undercutting those with crystal as boosted.. and they're not best pleased. And newbies looking for small amounts of tier I either pay dear, or get seriously frustrated, because they constantly have to post small and often.. and hope for the best, instead of being able to buy.
I do really think, after 4 years of playing... look at your situation, and build accordingly.
I now have 3 steel, 3 scrolls, 2 dust, 1 plank for elven tree gum ( I had two), 2 silk (for velvet).. and one gems (for I don't know what yet.. )
I'm heading into constructs..
I will probably be demolishing the extra silk, replacing it with a second gems.. and if needs be, first a dust, and then a steel will go..
A set up like this would have crippled me in dwarves..
Don't "even up" according to some formula.. don't even, even up according to inventory.. use what you have and build for what you need.
Be ready to change that.. long run, it works better.
And please, try not to back cross tier trade..
