Korf Audio have an interesting take on it, there ae 4 blog posts and a handy calculator.

Using the Ortofon calculations my 18g Schröder with an SPU Royal N should resonate at around 10Hz, on a HFN test record it actually throws a wobble at 7Hz lateral but nothing at 6 or 8Hz vertically, nor at any other frequency for that matter.
As above, use a Rega cartridge with a Rega arm and you won’t go wrong, they’re made for each other.
