I think the way that it works is that each of the two rings has 4 lengths corresponding to the 4 "teeth". Each ring combination results in 4 lengths that offsets the shaft in the head to produce the loft/lie shown in the chart. It would only take 3 lengths to get the angle so the 4th is determined by the other 3. The rings/head fit together well and seems pretty well made.
