Yes, and no.
One of the problems that has haunted Stack Exchange sites for as long as I can remember, is that some questions will go unanswered, earning OP's the tumbleweed badge.

You are right in the sense that Shadow Wizard is much more concise and helpful with each of his answers (in accords to the data).
However, since he responds less abundantly, it worsens the SE issue of leaving questions unanswered
The prime example (taken from SO):
*November 6th, 2017@11:55PM (UTC-09:00) Alaska
As M.A.R. said as well, it requires less effort to respond less frequently. It may simply be that Shadow Wizard responded to more questions with relevance than simply being more concise and helpful.
