Track of what?
IDK if the following will help, but he is quick minded with a good memory. He writes everything down during his work progress. I’ve noticed that he can arrange and order things in his mind in moments flat. Head work/videos or not. Jumbled information or not, an analytical mind set he has. *I Think* (I don’t know for sure) but *I Think* he has records for every head he has worked on.
@pittsburghracer , he makes no “YouTube” money from his videos. He does the videos for fun.
Edit- “YouTube money” as in paid directly by YouTube.
