Say I play three hours and it goes Win 50 first hour Lose 50 second hour Win 50 third hour Then before I leave, I play 15 minutes and win 200 in that timeframe. How can I incorporate this into my standard deviation? Thanks.

This is how you calculate standard deviation for sessions of varying duration. Let me know if you need the spreadsheet to do it.
