I was using my stackmat for some U perm practice, since I love them so much... O_O
I was easily breaking 1.50 seconds, and I was happy with that.
I got a 1.2x, and then I thought "I'm determined to sub-1 second a U perm; i know it will take a lot of accuracy with a lot of speed, but I should be able to do that."
My record was [I think] 1.13 seconds, which was insane when I got it a week or so ago...
Kept practicing, 1.11, PB.

It may have been a +2 though, but I wasn't sure. Very next U perm: 1.11 again. But this was 1 exact turn off, so it was a +2. Very next U perm:
1.11 AGAIN. This was definitely legit, and so I was happy with my PB (& 3 in row too).
Some several solves later, and a new PB:
1.09.
Now being happy about these PB's, I showed my nearby sister a little bit a speed that would get an eyebrow raise and a 'wow' at the least, but I was getting a small lockup on two tries as if there was really some sort of pressure. But then:
0.97.
!
I'm happy, but I know I'll break it soon after all of this.
If I ever sub-.75 a U Perm, I'll make another post about it.
---Oh, and this was done with a Rubik's storebought cube. My DIY's better, but for U perms specifically, the Rubik's seems to be better for it (unless I lockup).
---This U perm was with the Bar on the F face, and counter-clockwise.
