Interesting, between the current tracker thread (which covers roulettes finishing in 2017 onwards) and the archived one, I have three distinct roulette phases of about four years each.
In the original run of roulettes (the ones finishing 2010-2013), I was not very successful, only winning 1 out of 16 (6%) and even that was a joint win.
I didn't play in any at all in the next four years (roulettes finishing 2014-2017).
For the next four years after my glorious return (roulettes finishing 2018-2021), I achieved 6 wins out of 19, or 32%. Not bad at all.
I wonder what the next four years of roulettes will look like. I'm currently on 0 wins out of 1.
