Could be that we remember coincidences more than we remember normal things. However I have an example of the opposite.
I have won two nymphs out of at least 30 spins. For three of those spins I had not spun in the past few weeks (including my first spin). One nymph was won from a spin after a long time with no spins (1/3) and one was won during a spin-heavy week (1/27+). Interesting, hm? Of course, unless zanz speaks up, we will never really know. Who would be in a study where they give up their spins for a month?
