HL has nailed it.
D8 I here your frustration with the demise of private flying but the AFR is not the vehicle to carry it.
I normally cruise near 120 knots but for preliminary flight planning I plan on a cruise speed of 110 knots, that way I can ignore a headwind up to 10 knots.at 110 knots I get a flight time of 11 hours 36 minutes.
That's nice...but what is the point, you aren't actually "planning" anything your just guessing. Maybe you are like many of us who don't do a proper plan from year to year, if nothing else a good AFR is a wake up call for things like this.
If you resent a genuinely needed lengthy AFR then at least spend some similiar time in the room full of mirrors.
