Dan, one of the tougher and or time consuming part is being sure the player did not appear in a boxscore the day he was demoted. Some dates given for these transactions are incorrect. That is part of what I am doing with the years I am working on. Fixing/tweaking the depth charts, era rates, mgr profiles are a lot of work if done right. Lots of time and lots of simming. I really don't understand how the homebrews get done so quickly based on the time I put into these. However, I do tell my wife I am not real smart so the dudes doing them are probably heads above me in the brain department. Be patient and don't rush it.
