This is what I've decided to use as an upper-bound to the total number
of subscribers based on feedburner's definition of subscribers.
1) Take the average subscribers over the last 7 day, or last 30 days
depending on how often you post.
2) Divide the average subscribers from step 1) by the total number of
posts in the same time period.
My assumption is that most subscribers will read each post one time.
Those subscribers that read some posts more than once will cause this
number to be a little high. This depends a lot on your content too.
This also assumes that when they re-read they have to access your feed
again, but this differs for various feed readers. I would guess that
web based feed readers won't cache all the feeds. However, it looks
like Google Reader does because I've tried modifying a feed but the
changes don't appear. Feed readers could also cache a feed based on
how many subscribers there are according to them by using a lower-
limit of subscribers requirement. For example, Google Reader may not
cache a feed unless there are over 50 subscribers to that feed with
their reader (this is not necessarily true, just an example). In
reality, this calculation may be more accurate if most feed readers
(web-based or otherwise) do cache feeds.
