Not to me.   I set static by the book then adjust as needed to eliminate
pinging/knocking.  At most that is a couple of degrees.

After I'm done I put a timing light on it to see where the timing is at
high RPM when the advance is all-in... just to assure myself that this is a
reasonable number.  I do that because pinging would be hard to hear at high
RPM so best to be sure it isn't too advanced.

Of course 3s & 4s have different advance curves -- but if the 120-140 is a
static setting I would think the results would not be good.

OTOH -- if they are setting the timing at idle using a timing light that is
a very different matter as centrifugal advance comes on pretty early,
starting before typical idle speed.
