[Air-l] mea culpa 1, not 2

When I took my own advice, and ReRTFS, I realized that the heavy user
cutoff point was one hour (as someone posted), and not two.

Also, what none of us noted, is their three-way categorizing problably
underestimates heavy user effects -- if it had been 2 or 4 hours/day
instead of 1. (remember this is home use).

There are also boundary problems inevitable with an categorizing scheme
(as compared to regression): 59 minutes equals lite use, while 61 minutes
equals heavy use.

Apologies and goodnite.

Hope to see some of you at the ASAs in Montreal next week, especially the
CITASA section (Comm & Info Tech). Please say Hi.

 Barry
