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%View attachment 251678
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.
YAY! CLOSE THE PHUCKING THREAD BEFORE IT'S TOO LATE!

Wheels off to wheels on? Straightened springs? Arms and track bar readjusted?

You have done this before right?
Took me multiple days to do it right but I also fucked around with relocating lower shock brackets and moving them outboard as much as possible. Lots of racking and cycling.

I think Dave said he made his own towers that makes it easier without flipping.

If you can find any pics I would be curious. Knowing the little I know about an outboard and frenching the frame, there's not a lot of movement you can allow there that would be unique across tower options.

Dave places his tower differently than blaine does. Not sure if that makes a difference for the caliper flip question. Dave’s are leaned back behind the TB mount and Blaine’s are more vertical and overlap with the TB mount. Flipping calipers is nice because it gives more room for lower shock mounts to be moved outward which can only help right? I’ve never done an outboard so I’m just speaking out of my ass.

That's interesting. My understanding is you typically want to be close to 90* relative to the control arm. Seems like this is working around the work it takes to deal with the trackbar mount.

Do you know if Dave's is finished in that pic? I would expect to see the spring perch moved too. Maybe that's just but what I have been exposed too, but it seems like a nice to have.
Dave rotates the lower perch and leaves the upper untouched
 
I see we are now on to “Why doesn’t Dave do it like we do”. He does more of these than anyone I know of, except maybe Blaine. He is not taking the hard route. He is just doing it his was. It’s different, it’s ok. This continues to show it is not about brackets. Some folks don’t like Dave and try to point out any thing to discredit his work. That’s fine but why are you trying so hard? I don’t know Dave. I have messaged with him, that’s the extent of it. I have talked with Blaine. Both have helped me. Both do amazing things with a TJ. They have a different style. Choose what flavor suites you. This drum is worn out......

I have the same internet that everyone else does. I already did mine with Poly towers and flipped brackets. I can post pics of mine. I learned a lot from many members. Here is my thread.

As it relates to the two videos that keep getting referenced. Wheel Hop is due to wheels losing traction and quickly gaining traction and that loss and gain of traction can be caused by many other factors (not just antisquat). Such as tires vs surface friction, power to the tires for as it is related to that surface friction, Bushing deflection, and shocks, I personally am not convinced that the hopping in those videos is related to AS or the difference in AS between those Jeeps, I believe it is most likely more related to the amount of power being applied to the tires as it relates to the surface friction of that steep ass hill. Most likely any TJ with similar type of tire with the same amount of torque applied to the rear wheels on that surface would probably lose and gain traction and thus hop, the hop could be reduced by shocks and it could be exaggerated if there is anything lose or deflecting in the suspension. Just my 2 cents on those videos.
