Ed Bain has been producing stats for a long time. He concentrates on layoffs, claims, firsters, and a bunch of other categories. I find his material useful and he has been giving it away for a while. He does not study surface or distance switchers. Similarly, he does not study private purchases or ship ins.
He is starting a new service today which is incredibly priced at 18 bucks for 6 months and less than 3o for a year. I bought in and perhaps you might want to check it out yourself.
I receive no kickback from Ed. I don’t recall every meeting him or speaking to him. I have corresponded with him via email on a few occasions with questions about his material.
