Ok I dug through some old long arm vs short arm threads and found some calculations
@jjvw has done.
Here is a 4” lift with no geo correction. Antisquat in the 170% range

Here is Josh’s midarm. Antisquat in the 80% range

Here is geo correction. Antisquat at 117%

It would make sense that the 37% difference in Antisquat observed between geo correction and savvy midarm is probably bulk of the difference in hopping we observe in the videos. Happy folks? See how nice science and numbers and communication can be? Geo correction is roughly 50% lower AS than stock brackets, and savvy midarm is roughly 90% lower than stock brackets.
