thanks. fwiw, anything that's not easily accessible through batch processing (e.g. counting things) requires me to replay the events and monitor them in realtime. So several-hour-long recordings somewhat limit my enthusiasm to do so :) for pressure analysis it's easy, but for random things like palm misdetection I need a really short recording that I can replay over and over again until the culprit is found.
