basically i was just going to suggest, adding a **Join node** after the **buffer parsers** in order to wait and merge the 11 separate parser replies into one merged Object .. so you'll have all your values simultaneously available for calculations. This way you can avoid the separate joins and makes the flow a little cleaner. maybe 😉

ps. I didnt have your new flow imported at the time and my post was rushed so i deleted.  
and also you had other more important things to sort out (with addresses and offsets) and i didn't want to side track the thread.
