Yup everybody is ignorant about the operation of engines except you
Adam flies an Aero Commander 520. It has GSO 435 Lycoming engines fitted with pressure carburators. His reported fuel flows are the best you are going to get from this engine. All the modern engine analysers in the world are not going to make any difference as this engine won't run smoothly at LOP.
In any case all the private pilots I know who operate twins are quite aware of how to run the engines economically because they are the ones who have to pay the big bucks when the fuel truck pulls up! They all have and use engine analyzers.
