I was simply pointing out (with which you seemed to agree) that for the route you gave it doesn’t seem to give a better route, or better fuel management or necessarily a gain in TAS and it doesn’t give you a higher crossing level.
Then you have a very poor understanding of my route planning, the performance of my aircraft and the significant gains from flying high that I gain. As pilot in command I choose to fly a route in the most expeditious and efficient way. As I am not limited to VFR only I have a wider range of options available to me and use the most appropriate tools for the job on each flight.
Therefore I suggest you stop speculating before you make a fool of yourself.
