This fact on its own is not enough for some people, they want to know how many seconds that is per week. Well I think about 374 Saturdays have passed since my first. Assuming I just need to divide one of those numbers by the other I get a score of 2.58 seconds improvement per week.
Should that number ever drop below 0 then I’m afraid it will kill this webpage (if not the entire site), to prevent that I’ll have to set another PB before 2034-06-12 .
