I've a little bit periodically over the past few years.
The most I've ever done is 20m at a time, but every day.
I've had the same reservations as you, is it doing any good, how can I tell? It is trivially easy to be wrong.
I do like something I see in the people who are more advanced practioners and I keep being drawn back to it.
My latest thinking is that since I can not for the moment find anything longterm to measure, I'll do it for the immediate enjoyment I get directly from the session - from physically relaxing if nothing else. This has now made my sessions very short, just a few minutes at a time before I stop enjoying it.
I'll add another recomendation for "Mindfulness in Plain English", I like it a lot. I'm slowly consuming it, reading a few paragraphs before each meditation session.
