Yes I found his limitations reflect a technician’s perspective and understanding of the measurements he takes and the claims he makes. I find his resistance to change does not reflect a scientific approach. His lack of curiosity is disappointing in a role purportedly for social benefit. I shrug my shoulders and have moved on. I have learned a lot about electronics electrical theory and quantum mechanics as well as materials science through research and reading beyond ASR. I learned none of this within ASR. Basically I’ve stopped bothering with him or ASR as a source of information.
YMMV.
