is 'complete lesson' worthwhile to go through, to pay for, or at least 'advantage'?
i think that from a certain perspective it can be.
1. readying for a shot.
3. pressing a trigger.
4. reloading a gun.
each of these lessons is worth something, has certain value in itself, but together they are worth more than sum of the parts.
so called 'synergy effect'.
Dragonfly Algorithm is part of something bigger, 'complete lesson', perhaps.
i have insights suggesting this occasionally.
'a warning shot' in the air also has it's uses,
perhaps does not require so much of an aim ...
