Moreover, to create "symmetrical" shapes (symmetry relative to the X axis) like many gates (and op
amps) with even number if inputs, you often need to place them at y = + 50 mils and y = -50 mils and
100 mils step between pins, therefore using the 50 mils grid

Using (to place pins) *a* 100 mils grid is not using *the* 100 mils grid.

So starting on a 100 mils grid is not a good idea.
