Yep. I automated mine about 7 years ago, but decided after a few months
that it was easier to start it up manually. An intermediate step I
included was the -R so that it would continue if there was one to
continue, but found this was not a good idea when a screen session was
"available" for reconnection but had somehow become frozen. (SunOS v 4.x
with screen and admin upgraded libs/patched system while stuff was
running.)

I now go manual since I am most often reattaching to a screen session with
all my stuff running as it should.
