Far be it for me to claim perfection. Massive paranoia and not enough money to replace the plane have held hands and protected me from my own stupidity so far (don't give up on me guys
)
I consider the last hour of fuel in the tanks as contaminated from never having been burned off in the decades I have flown the old wreck and is unfit to enter the carbs.
Flight distance is by my watch - not distance. The distance to some particular airport has nothing to do with it. Bingo time is bingo fuel and we land. Did that 20 minutes from my home field one night. The guy with me was foaming at the mouth mad because he would now be 20 minutes late.
Some people do not have the mind set to survive flying. Luckily he ran out of fuel a couple of times with only minor damage and the wife put an end to his flying before Murphy did. Heard later he had to be towed back to land more than once in his yacht (shrug) after taking up boating.
