I made a QRP entry for ARRL SS CW. It was my first significant effort since 2001 and a near match for that year's result. I claimed 198 QSOs and scored around 26k. Spent most of my time on 40, followed by 20 and 15.
As mentioned here, I got curious about the check pattern and did a little calculating. The only way I can read this result is that CW contest aficionados are aging. I don't suppose this comes as a surprise.
Number of Years Since First Licensed (mean±SD)

I received just one check from the 21st century. That's about one-half of one percent. Kinda gloomy.
