How many times do you pick in a day?

I've been asked by my therapist to take note of how frequently I pick at my skin. I kind of do it continuously, so it's hard for me to keep track of it. However, I counted that I felt an urge to pick about 70 times today, which feels like an insane number. I'll keep counting for the next couple days, but was curious to see if anyone else here has ever tried to keep a record of their skin picking habits. How many times do you do it in a day? Is it just for a few minutes, or for hours on end?
