How do you all quickly and accurately count the number of pairs when brushing multiple gears?

It feels really easy to count when brushing low gears, but when going up, my whole mind goes blank.

Brushing alpha trading times makes me dizzy 😵‍💫

I counted back and forth 7-8 times and it still shows I'm a little short.

Every time I finish brushing, I count again and it still shows I'm a little short.

I'm exhausted, boo hoo hoo.

Is everyone else counting like this or how do you count, boo hoo 😭#alpha
