How often do you cash out?

Ever since they added the $2 fee to cash out I’ve been trying to figure out the best way to cash out to maximize my earnings. Based on last 30 days my average earning per sale was $28 and $885 in sales. I try to let my balance get up to $600 and then do an instant of $3 because the $1 different seems so minimal. Sometimes it takes me longer to get to $600 though and I’m in need of money but $2 off $28 sale is pretty high and some of my sales are as low as $8. Has anyone found a way that seems to work best for you to maximize earnings? Luckily I’m not in the position where I need to cash out after each sale anymore.

tldr: how do you maximize earnings with the $2 cash out fee?
