```I took SEAOC's recommendation to prepare wood design in LRFD.  It may
be the way to do wood design eventually like or not.

So I got to the NDS Table N1 on page 170 for KsubF to covert ASD values to LRFD.

Why are the Ф (resistance factor) in the devision part of the adjustment?

For connections the multiplier is already 2.16.  If a resistance
factor 1/0.65 (connections) is also applied, it will become 2.16/0.65
= 3.32.

What is going on?

Thanks
