Doubt you'll find many pilots who know how many minutes they hand-fly!
Generally speaking, as long as:
the weather is ok
I am not tired
there is nothing wrong with the aeroplane
I am familiar with the airfield
we are not in a busy TMA
the captain is happy for me to do it
then I hand-fly every departure (to a few thousand feet, but I engage the autopilot before levelling) and every arrival (from about 2000-3000 feet agl).
I fly the Dash-8
