They don't. They make it more progressive by laying the bridge pin 
field back towards the rear of bridge cap area on the high side of 
the strut and vice versa on the low side, but not completely so, 
since they are not prepared to build a severe enough dog-leg to 
accommodate a uniform increase in the speaking length.

Note that a typical note to note spacing within the bridge section 
will be between 13 and 14 mm, whereas the note to note spacing for 
the two notes adjacent to the strut will be around 32-35 mm. 
Therefore, if the speaking length is to increase progressively, there 
must appear to be a significant dog-leg in the lay of bridge pins on 
the bridge cap. Just lay out a test scale onto a straight strike line 
as an experiment. All will be revealed.

Does that make sense?
