Hi again, pgood1947 - I see you posted something similar elsewhere on our COPD.net platform, for which I was able to provide a reply. For your convenience, here is a link to that comment I made: https://copd.net/members/pgood1947/status/91490#upsr-72836.
I do hope you have an opportunity to look it over.
Warmly,
Leon (site moderator COPD.net)
