Help Understanding Something

With the ongoing 20% affix event going on until NGS launch I would assume that means anything 80%+ is actually 100% (since that 80% was 80% prior to the event starting I have to assume it's just in the background)

However, in upslotting my new units I had it fail several times even at 80%. So what's the deal? Is it broken atm? Or does the 20% only apply to normal affixing and go away when trying to upslot?

the 20% is applied directly in the percentage success so if is showing 80% the real value is 60% + 20% of the campaign

Okay so it is baked into the stats being shown. That's odd because I could have sworn it said 80% before the event actually started which is why I was so confused over this. Thanks!
