Thanks guys - great stuff!
Like I said, the idea is to develop a better understanding of the power difference among various flight regimes.
I specified 'standard day' only to remove the OAT dependency (that many of you correctly noted) from the question. I think I have enough info from POH on performance-vs-OAT dependency to extrapolate from the standard day if needed.
I will also do some flying with a notepad and will post here what I get.
Thanks again.
