Output of Dual-coil pickups

[Wayne27]

I read that the dual-coils of humbucker are supposed to increase the output of the pickup, but I also read the duo-coils reduces the output of PAFs.

I'm still new in learning the structures of pickups.

The two coils of a humbucker have less output than the same amount of wire in one single coil because they have a lower inductance (twice 5000 turns of wire around humbucker bobbins are approximatively 1/3 less inductive than 10000 turns around a single P90 bobbin).

But the two coils of a humbucker have also twice more inductance than a single coil hosting 5000 turns, obviously... and therefore more output. Splitting a humbucker should illustrate what I mean.

So, it seems justified to say that two coils increase AND reduce the output. It depends on the starting point selected as a reference.

Now I understand! Thank you for the help! I have so much to learn about pickups.
