I would think this belongs in "The Website" forum rather than "The Author", but the answer is --- as best as I can calculate --- each recent chapter is emailed to 166 recipients and has been downloaded via browser an average of 200 times.
Edit: the latter is a count of unique IP addresses, of course; approximately two dozen people have downloaded it multiple times.
