Just last Saturday flying out of Nephi Ut in the flats of the valley over Yuba Res I had a thermal kick me into a 80 degree bank.
Full roll control wasn't enough so I pushed to about .1 G and full ruddered it back level. I've done this about 100 times in my soaring career.

Wow! That's never happened to me! In 6000+ hours of flying all over North America
- never have I been pushed more than 20 degrees or so. Just luck can't explain
that difference, so I wonder what we are doing differently that I've never been in
danger, and you've been there 100 times.

I have had some upsets of this magnitude. I remember having my (glider's) tail lifted nearly vertically. I have also encountered roll clouds that rolled me 90 degrees.
