I-cord bind-off on Haruni

I tried to calculate in my head the number of stiches needed to complete the I-cord bind-off but failed. I'm normally pretty good at math but something told me not to figure this out. With an extra repeat on the basic pattern I must have at least 100 loops to make (of 8 rows of 2 stich i-cord).... I'm lost again.

The good news is that it's completed and the next steps are to weave in the ends and block it.
