Now I think I understand what SeaQueen (and probably more DW users in the past) had done.
[2] Pen, paper and Bearing Rate template solution.
I think I could use an A4 squared sheet and a pen and make myself the time/bearing plot. But then I will need to use a Bearing Rate template to measure the bearing rate... Any idea on how to build one?
[3] Custom software with a GUI (let me dream...)
The more advanced solution, would be a custom software in which to input the time/bearing values for a segment and then get the faired bearing and the bearing rate as output. Well, at this point, of course, step #2 would be to give the software the ability to record/store a set of segments (TMA legs) and to compute the Ekelund range and maybe some other stuff... I've dreamed about a LOS interactive display to formulate and test multiple hypotetical solutions concurrently...

The most efficient solution in dangerous waters is:
i) Determine the bearings from NAVmap every 2 (1 in new RAmod) minutes.
ii) Calculate the bearing rate with a pocket calculator.
ii) Knowing how to interpret the data.
ps: double leg Ekelund range formula, requires at least 16 minutes.
It's better determine the solution in tma station.
