It doesn't really even have to be 6-8 encounters. It could easily be as low as 3 deadly encounters at a reasonable difficulty.It’s just hilarious that people keep complaining that the game is not deadly enough whilst at the same time refusing to use the recommended amount of encounters. I understand that for more story driven pacing six to eight encounters per day will never work, but ‘gritty realism’ is for that.
Actually, it could also be 1 super-deadly encounter as well, but this approach is far more absurd and I'd recommend against it unless you're comfortable having a level 5 party fight a Purple Worm or Death Tyrant for the day.
Its totally possible for them to be victorious but you'll find player death to be much, much more common going this route.
