Mahasi noting is the most meticulous practice I've ever done. It's easy to do wrong and should be done with a trained teacher. There are Mahasi centers that offer month long retreats which are worth exploring (at least when the pandemic is done).

The first time I did a noting type practice (way before doing the Mahasi style of noting) I became nearly instantly depressed and disassociated. Noting is, for me, a very agitating practice. If someone is reading this, this doesn't mean Mahasi is a 'bad' technique. But you may want to steady yourself in a shamatha practice before considering noting.
