I think that Jerry.J.B. has missed the point of the apidictor.

When it tells you that the bees are planning to swarm, it expects you to
open them up there and then and take your swarm avoidance measures.  You do
not send a message back to base to be actioned in the future.

In his last paragraph he says that if all swarms could be prevented, one
wouldn't need a warning system.
Surely, it is the other way round!   The purpose of the warning system is to
allow you to prevent all swarms.

For example;  one swarm prevention method is to divide the colony into two
brood boxes, one above the other.  I cannot remember the exact details, but
one half has the queen and the other has the cells. The colony thinks it has
already swarmed, you do not lose any bees and you do not spread your varroa
to anybody else.  Then you can either separate them and have an extra colony
or re-unite them with a new queen.  Either way you gain in honey crop.

You must have a completely different philosophy from us due, no doubt, to
the enormous distances between bee yards and what the management men
describe as cost/benefit.
