As far as checking the rudder angle indicator, I agree with @Ausmariner that it depends on where it is located.
On the ships I was on the rudder angle indicator was located where it can be easily seen by the helmsman, directly above where the pilot typically stands. Checking the indicator requires the pilot take half a step back and craning their neck up to see it,
In my experience pilots do not check the indicator unless they see or feel the ship turning the wrong way.
