Wow, they went overboard on those magnets. I just took out another 4, that makes 13.
I figured that the cover was uniformaly magnetized, like those business card magnets.
Not so! The front and rear cover have embedded super strong magnets at certain points.
The right side of the case has about 10 magnets, but only 4 interact with the front cover.
So, for all the people who are replicating this (i.e. none) you can take it down to these four magnets.

I'm waffling on installing a foot as those dollar store cell phone stands (like plate stands) works pretty dandy too.

Note: And I finally figured out the cover Hall effect on the Poke3.
There's a little sticker on the right edge, like a store anti-theft thingie.
But it's not magnetic. Is it RF? I couldn't figure it out. (It's just a pad.)
Like the Poke5 cover having a fiberglass? acryclic panel with super magnets, the Poke3 is the same.
There is only one magnetic spot, not the right edge, but slightly right of center on the bottom edge.
The Poke5's spot is on the bottom edge on the left.

Watch out for those case magnets on the Poke5.
They are very strong and can easily wipe the stripe off your credit card.
The cover magnets are not nearly so strong.
