I recall doing a numerical approximation to something, and it seemed to converge to about 2.5
Enough for me to, in my overconfidence, assume the constant was 2.5. Later, when I found an exact derivation, it turned out the actual constant was pi^2/4 or 2.46740110027. Which was apparently close enough to fool me.

- mjd 6y agoA while back I looked at a problem where Monte Carlo simulation said that the answer was probably 4. But analysis showed that the actual answer was 9304682830147 ÷ 2329089562800 = 3.994987…. https://blog.plover.com/math/breaking-pills.html https://blog.plover.com/math/breaking-pills.html
