Well, firstly I must thank you for posting this update, Jono -- I am very interested in this series 👍
Secondly, I have to admit that I had to veto the first of these two videos due to the mathematical content. I have always hated maths, logarithms, sines, cosines, tangents, algebra, tables, lists of meaningless (to me) numbers, etc, etc, etc...
However, the second video (above) was most entertaining and I look forward to the next instalment of 'Land Rover Restoration' 😊
