Hi Bob,
I think your email was addressed to Harri, correctly re the graphs and computer images. I am happy to send you details of my successful build using Harri's current (version 3) graphs if you want. Your ideas sound interesting and I await replies from Harri to you and any further improvements of the graphs.
I'm getting 2-5' accuracy, in under a minute time for Hc and no problems with the current model which is similar to the original. Easy to read with practice. (so far 20+ Hc calculations)
Best wishes
Francis
