No, it doesn't.
A 1461 day moving average would. Or a multiple of that.

A day of difference would be a day of difference. During the fast changing season periods the change is 2x the annual average change. High daily averages top 100k per day. Divide that by 10x and you get 10k per day - against the max variance of 150-200k. That is significant.

You were looking at it. The northern hemispheric sea ice extent data shows a quite clear 22 year full cycle (or two individual 11-year cycles).

Your first paragraph is simply wrong. The chart looks identical with 9,10 or 11 year moving averages. Data source is there if you want to plot it up yourself.
You can’t see a 22 year year cycle on a 10 year moving average.
