Rob,

You apparently have a good deal of confidence in your building and 
assembly skills - that is great, but not all have the same confidence 
level, and the checks at the Low power level are important to those who 
do not also have that confidence level.  The manual speaks to the 
"lowest common denominator" so those who need verification that the low 
power stages work properly will have that validation.  The result is an 
orderly process - the basic K3 works, and if the KPA3 causes problems, 
one should look to the KPA3 or the steps that were done during the 
installation of the KPA3.

For those who have great confidence levels (and good troubleshooting 
skills), you are free to do it any way that works for you.  For the 
average K3 builder, the situation is not the same.  Consider the K2 
situation - I have confidence that I can find any problem in a complete 
K2, so if I build one for a client, I skip the intermediate test and 
alignment parts, and wait until the assembly is complete before 
beginning alignment and test.  That approach usually saves me time, but 
at times it causes me to dig into the K2 to find what is the problem 
source.  Yes, my experience level allows me to do that efficiently, but 
new builders do not have that experience level - hence the instructions 
are geared to test the configuration that has been assembled before 
moving to the next step.
