The only problem you can run into if you do it every minute is in longer sessions, it can take longer than a minute to import since it still has to go through all the hand histories in the file and just load the new ones. This means it starts a new one as soon as the last is ended and you cannot get control of PT to stop the import timer. I usually set mine to 3 minutes and I even in my 4+hr sessions have about 60 seconds between the last import and the next one starts.
