@meno I believe the actual reference to experiment was about this:
https://steemit.com/cryptocurrency/@zac2116/30-seconds-to-win-1-eth
As explained here:

thank you for these links Eric... i found the medium article too... but no the steemit experiment.
:)
@meno the calculations made my head hurt... Perhaps someone that can understand it can clarify? I think that was the experiment.
