Sorry Art, but I disagree.

I should point that the discussion was about normal cruise not full
throttle, maximum RPM.

The POH says that at full throttle you should have gotten 163 knots at
14 GPH, which certainly points up the inaccuracy of the POH numbers.
While the difference between 161 and 163 is minor the difference
between 14 GPH and 16.6 GPH is 20%.

certainly points up the inaccuracy of the POH numbers.

I don't disagree. However,the numbers for lower speed & fuel flow are accurate
enough not to be a problem.
The disparity in claimed vs actual performance is no worse than that of Cessnas
or Grummans that I've flown.
For that matter, the the EPA fuel figures for all my cars have always been
unattainable
