very kind of you to also include a metric that mathematically challenged alchemists such as myself can work out on the back of a napkin in fifteen minutes. track and multi arms take up a lot of space so ideally this would be period 4, seems easy enough....

...that was definitely too easy, and with secondary and tertiary metrics being what they are will be a fifty way tie. so there is a period 3 solution out there. with input, outputs and mandatory disposal taking up 13 hexes already someone is going to really have to work to get that 90 or 87, and it will no doubt look extremely silly. not me tho.
