I think you missunderstood me, It is safest to carry flight plan fuel to desired destination(plus extra if needed). I did not say I have never refiled enroute or done critical point planning. I did it in a business jet where if I did'nt, the passenger wasn't going not just his underwear. I also knew this aicraft could be flown at long range cruise and save significant amounts of fuel.
We have all compromised ourselves at some point to the god of commercial pressure but to think it is perfectly safe and normal is self delusion.
