Question - How do you flightplan extended spousal cross-country flights?

Is that non-turbo?

My TCM engine chart (for turbo) says
about 12.2 gpm for 72%
Rich limit around 13gph lean edge around 11.3

9.5 gph on a turbo down around 55%

So yours is non turbo?

Or is that 'hard' LOP ops?

After 27 years w no engine analyzer,
next upgrade I'm thinking about is an engine analyzer.

But ...needs to be what, $12-15k of benefit to justify it?
