Yes ,we first discussed this in January I think. I was then ill for a while, in and out of hospital, and misplaced/forgot the communications (going senile too!). Apologies. Now back on track I hope!
I hope to adapt your methods for sailing to Scilly Isles next spring. I hope to try the final version Brown-Nassau, the Polhemus, the Bygrave and Doniol Hv. Should be interesting.
Thanks for all your help.
We discussed this before, see:
I give a detailed explanation of the use of the MOO and MOB tables here:

Chichester didn't do his precomputations prior to takeoff, he did them in the air while holding the Bygrave horizontally so he didn't prepare any altitude curves. He did post his verson of the MOB (Motion Of the Body) correction table, which he calsulated himself, that he had pasted inside his cockpit. On your voyage you can avoid drawing the graphs and use the MOO correction instead. Any you wont have to calcuate it yourself since I posted it before, see:
