[Schiendelman]

I'm reminded of the adage about getting 80% of the way through shipping a product, and then doing the other 80%...

[fouc]

Yeah that's what I was referring to, the last 10% takes 90% of the time. Or the difficulty of getting from five 9s to nine 9s.

In this case the final 1% is 200x harder than getting to the initial 95%.
