My espresso machine is much cheaper than yours so I can't really comment on the $$ on grinder vs machine ratio. I am very happy with the Zero and do not feel any desire for a better grinder. I can say that the grind on the Zero is similar to what I got out of the OE Pharos but the workflow is worlds better.

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

Different types of grinding use different methodologies to determine the work material removal per unit of width, but one consistently useful metric for shops is the grinding gratio, or g-ratio. This is the ratio of volume of work removed to volume of wheel consumed (or, volume of work removed ÷ volume of wheel worn).

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid […]

An even simpler formula that's used in calculations in just about every grinding process is the specific material-removal rate, Q', known as "Q-prime." Q' = a e × v w where a e is the DOC measured in mm and v w is the feed rate measured in mm/sec. The specific mrr is the total mrr per unit width of the grinding wheel.
