it's a funny thing... it can be 5 seconds and it can be a week

i was vanity mining for my current npub and i'd probably run it for 2 or 3 days and then one day after i'd given up for a week i run it 5 minutes and bam!

it's hard to explain how it works but "a few days" "average" are quite vague compared to how it really works - "average" is the peak of the bell curve and that thin edge can mean literally weeks or seconds
