I am not so sure that using selling days is not a legitimate practice.
Cars are sold only on selling days. So this may properly adjust for the
number of days that cars can be sold on during a particular month. This
may be a proper way to monitor sales.

Personally, adjusting for the number of selling days is ok, as long as
one considers both the adjusted number and unadjusted numbers.

That's a good analogy.
