Getting through commercial airport security after obtaining a pilot cert

I am curious to see if anyone else has experienced an increase in the
frequency of being selected for more thourough security searches when
flying commercially since obtaining a private pilot certificate.

I am not a paranoid person, and am not really bothered by it but... I
am well over 6 feet tall with blonde hair and have not changed my
travelling 'style' in the last 5 years. I fly about 6 times a year for
business, always round-trip, most of the time planned in advance.
Since obtaining my cert a while ago I seem to consistently get pulled
aside for more intensive screening. I am just curious to see if anyone
else has encountered this.
