Let’s try going from contrary. You said 2 in 72. Imagine a situation when it’s 72 in 72, which means, 72 years straight, each year had a three-year streak. This doesn’t make any sense. Surely the maximum amount of three-year groups in 72 years is far fewer than 72.

Hmm, good point. I suppose you could count `0,1,1,1,1,0` as 2 occurences of 3 consecutive 1s, but we'd probably call it a single quadruple niña event instead, so I see where you're coming from now.
