6/6/6, only one axis with linear 4-movers, but there ended up randomly being two niss 3-movers, which I only found after writing 50+ eos that I didn't end up checking. Everything I found on the attempt was from one eo.

First I found this:
(D) L' U
F, U2 B2 R2 U2 B2 U2 L // 11 2c3 2e, infinity variations
or
F', R' U2 F2 R F2 B2 L // now 2*infinity variations

Then I found this:
(D) L' U
F (F' L2 F U2 R2 B) // 10 4c3
Not good enough to check immediately, and I ended up never looking at it at all.

Next I found this:
(D') L' U
F R (F' L2 F B2 L) // 10 2c4
I wrote an immediate 25 from this and moved on.

After this I hadn't even close to exhaustively checked the 3-movers, but it was at 30 minutes, so I went to my 11 2c3 2e variations and started spamming stuff. I got so caught up in the variations and I found NOTHING AT ALL! Cut to 55 minutes, I write out the 25 from the 2c4 on my submission sheet to avoid DNF. Then I realize that I haven't even looked at inverse on this 3-mover, so I switch it and immediately find
(D) L' U'
(B' R2 B2 R2 B' L) // 9 4b2 4e
Literally 56 minutes into the attempt. I don't have time to mess around and it isn't close to trigger on inverse, so I immediately switch to normal incase it's free on normal, and it's one move from the 6 move trigger
D2 B R2 U2 R2 D2 F' // HTR in 16
L2 U2 B2 L2 // slice in 20... or so I think
2.5 minutes left in the attempt and I find a slice in "20" and don't realize it cancels with inverse and is slice in 19 actually. I do the riskiest slice solve of all time. I'm constantly undoing and redoing moves trying to solve this slice, unbelievably lucky that I didn't do something wrong along the way. I find a +1 and immediately start writing it down, I don't realize until I'm 14 moves into writing the solution that inverse cancels and I actually have a 20, not a 21. I finished writing at 59:57 thinking there was a ~70% chance it was a DNF, but it was my lucky day.
