Full Version: Approach to calculate TWD?

I was wondering about what approach to take to calculate more advanced wind parameters like TWD. These calculations could be performed on a few places in the setup but where should they be performed to get high accuracy as well as easy distribution of this data to consuming apps? Is there a preferred way to achieve these calculations? 

For reference my setup is 
a basic Raymarine setup with wind transducer, log and compass connected to a simple i70 display. I've no Raymarine processor other than the autopilot. The system is connected over seatalk/n2k to signal k.
Perhaps Node Red?
TVR recommended the derived data SK plugin.
Works ok for me with Raymarine ST50 instruments via a Seatalk-NMEA converter
