Is grinding an S rank 0->1 w/ 3*+S10 100%?

[DPShiro]

Or is it 99% or 99.9999% etc?

Yes, the same odds ass using an A+10, B+10 or C+10 grinder.

I've done a fair bit of grinding and I've never broken when it says "no chance of failure" so I don't know...I know people claim to have broken at that "no chance of failure" level, but until it happens to me I refuse to believe it.
