Scott,
Every ATU design has different stray amounts of L and C. But the differences
are small between the KPA1500 ATU and our other ATUs, especially the
battlefield-proven KAT500, which has a virtually identical circuit. We test the
ATUs into various loads to verify matching range.
That said, if you believe yours has a matching range problem, please contact
support. There’s even the possibility it’s a firmware issue.

I've also noticed that the ATU often doesn't get a very good match, even if I
try twice as per the manual. The K3 ATU, by contrast, usually finds a much
better match for the same load. (Not talking high load SWR here, less than
2:1.) I haven't compared the component values in the two ATU's, but I expect
they're similar, so they should be able to achieve equally good matches.
