I am trying to understand how to knit a hat.

As the pattern below mentioned : https://www.craftsy.com/knitting/patterns/hope-hat/167831

’Knit 9 repeats of the braid, or until the cables band measures 22 inches.’ , and the Crown: pick up and knit 72 sts., etc

I just can’t figure out how did you have 72 sts pick up if have 9 repeats of the braid.

Each repeat have 12 rows. If 9 repeats, I would assume it has total 108 sts pick up.

Here is my question., if I customize my own fitting on the cable band, then how many pick up sts I need to pick up and how to do the decrease round etc?

Thanks
