Lehto's videos have some crucial misunderstandings - such as about focal length and hyperfocal distance central the point of his first video (https://i.imgur.com/8xAjbgg.mp4 https://i.imgur.com/8xAjbgg.mp4), and about weight affecting load factor in his latest video (https://i.imgur.com/n5vOzZI.png https://i.imgur.com/n5vOzZI.png). With corrections, people are getting around 15nmi using the same technique as Lehto. Lehto seems intelligent and has very relevant experience though. I think he just made the mistake of jumping straight into the debate shortly after seeing the videos, when West has had years.
