# Does getting two upvotes very often denote serial upvoting?

So, very often I have seemed to get exactly $2$ upvotes for a series of problems, but in no particular order in large quantity. What I mean by that is:

Out of my 23 answers so far here, I have recieved 13 answers with exactly $2$ votes.

Now, I feel that often times, the answers specifically do not deserve the upvotes, etc, but I am not complaining. Is this phenomenon common, or am I getting serial upvoted?
