it's really all about varroa mites, and whether or not one is employing any measures to assist the colony in dealing with varroa mites.
definitions are all over the map and the position of the forum is that there isn't any future in debating the definition.
the founders of beesource came up with the working definition found in the 'unique forum rules' which are stickied on the sub-forum main page.
that definition is not satisfying to all by any means, but represents the best attempt by those contributing at the time.
i personally do not employ any method be it chemical, mechanical, artificial brood breaking, removal of drone brood, ect. most of my frames contain 5.4 rite cell foundation, although i have a few foundationless frames scattered in the mix.
about the only manipulation i employ at all is the promoting of broodnest expansion during the spring build up to prevent swarming; and this if anything would be counter to limiting varroa mite population growth.
as has been stated so much of this has to do with location and goals. i can appreciate how for many it's just easier to treat on a schedule and not worry about it.
my hope however is that just as many or more will heed the call made by randy oliver to do what we can to move the ball forward in terms our management and selection for more resistant bees that are less dependent on the beekeeper to survive varroa mites.
