Welcome to the list and congrats on the new Dak, Steve.
The oil pressure dropping at idle when warmed up is normal. I noticed it
as well
and my son said that it's computer-controlled. I'm not sure if the reason
is to
reduce wear and tear (oil pump) or to control emissions (lessen blow-by gases)
at warn idle since high oil pressure isn't needed at warm idle for engine
operation.
