Hahaha - had a good laugh at those and recognised I’m guilty of 9, 8, 4 and 2 :). In fairness I only once set out on a run with the purpose to improve my time on one uphill Strava segment. I got 2nd, but was humbled when I saw that first place hadn’t done what I did at all. He’d done the opposite - with a very hilly 15 mile run, averaging miles quicker than I could on an all out 1-mile flat effort :D
I do like round numbers though. - I don’t run 4.95 miles, when doing the extra 50 yards will get an even 5.
