Guys volunteer to rebuild schematic libraries have already done a good
job and have spent a lot of time (and many mails) on the "best practices
".
See:
https://github.com/KiCad/kicad-library/blob/master/KiCad_Library_Convent
ion.txt

therefore:
offset between pins = 100 mils
grid to place pins is 50 mils (the pin themselves are on a 100 mils
grid, but you sometimes have to use a 50 mils grid to place pins at
positions symmetric to the X or Y axis, like in 2 input gates, or Op Amp
s)

Automatic insertion of pins have to comply with that.
