I'm sure I'll be bashed for going against the grain as a beginner but its just my experience so far, good luck!
WHY is that..?.. your expectation?
Experienced same..?... as it is your *thing* in going against what
is known, written in stone?
0r are you posting a challenge?
Wrong subforum for that... this is beginners, where rightly
what is known to work for everyone should be the content
of posts.
That 3/3 rule..?.. it works, for _everyone_.
Nobody can be certain for sure as it is only you onsite buuut
for way more instances than n0t it has been my experience
where when told "0h there were n0 flyers" that remark has
come from not knowing, not looking 0r not knowing where to
look.
The are many methods to move bees, varied outcomes apply.
But one thing holds true... don't reset a forager's mapping plan
and there will be loss and/or drift.
It is that degree of drift which truly determines the success of
the shift. And frankly in many a year I have yet to meet or hear a
backyarder discuss this in any depth. Either it is n0t known
or n0t cared for, in knowing.
Forgive the presumption - supported by your posted outcome -
I have just read another. There are way way more than 30 foragers
in any colony running around after 10AM. Trust that.
