True to what you are saying and in regards to my reply post. It is not complete 100% absolute bullsht. I certainly believe the forgery analysis studies, and very interested in it's details and scientific approach.
If something is admissible in court, does not make it void of bullsht. Expert Witnesses, for example, come in many shapes and sizes and are paid to testify. They are not witnesses. They will describe something because they may have built one of these for many years. I know a few dudes at my work place that just get by day to day with minimal work and craftsmanship for years. And a few dudes that bust ass everyday and are very efficient and productive. There are many variables to consider between all of this.
Today, I wrote down some notes while someone was talking about what they were talking about,
Then wrote in an inventory log for future reference regarding parts and components
Then wrote down a list of what I needed to do after work
All handwritten and all in completely different styles for purpose. All in different locations with different audio, distraction, sitting, standing, outside, inside, lighting, etc. combinations and within 15 minutes. With the same hand.
