80% epic potential explosion rate?

Yes, I am aware that the scroll says "Will explode at a 20% rate if the scroll fails" making the true probability 4% of explosion.

HOWEVER, I would like some confirmation that people have actually had items survive after the scroll failed.
Why?

2/12 scrolls failed for me, both exploded.

Has anyone had 1, or maybe even more, epic potential 80% scrolls fail and NOT BLOW UP YOUR ITEM?

Thanks.
Personal experiences only please, no he said she said garbage.

I also realize the explosions could have been due to luck, obviously.
I just want confirmation that people have had items live after a 80% failed.
