I do not practice samatha meditation anymore. I practice a different kind of meditation now.
We basically have 2 kinds of meditation.
1) Concentrate on a thing for a while.
2) Watch sensations come and go while refraining from moving your attention in reaction to what you're watching.
I did the first for a few years. Then I did both for a few years. Now I only do the second.
Both deliver the calm but they do it differently. They also do some other stuff.
The second is trickier than the first.
