I feel like there’s some software adage about the last 10% being the hardest. It certainly holds true from my experience - even if they are 90% of the way there, it’s not a linear path to 100%.

90% done, 90% left to go.

so the 90% is really meaningless in that case.. it's what we judge to be 90% which is erroneous.
