No
I spent a couple of decades baby sitting a room full of HP K200s and K380s
Experimenting was not something done lightly, if you valued your job
You stick with what works
Typing sync twice was advised and I was not inclined to anger some unknown god
Using sleep between operations is as you say experimental
I wrote many scripts that ran as cron jobs at night
I was not concerned with speed
I've been retired for almost a decade and do not miss the sleepless nights
