Interruptions don't matter because the rest and recovery rules are so loose you can't backslide into a death spiral where more is lost than gained. With how low the bar is for short rest class nova to recharge & at will unlimited cantrip casting it probably doesn't even matter if the gm interrupts the rest with anything shy of rocks fall lightning strikes death by massive damage or an endless parade of ancient dragons opening with surprise air breath attacks.
You don't know the specific situation, so you can't say that with any confidence. Depending on what is happening, a lot more can be lost than gained by an interrupted and delayed rest. Especially if the random encounter is a hard one. Random is random. Could be one goblin, or it could be an adult dragon.
All of that remains true until the gm trolling their players like that murders the session trying to stop players from taking the rest they feel entitled to and totally justified in taking.
I don't know what you are trying to say here.
The time pressure the players have already decided they don't care about? Making it matter dives into a whole different rabbit hole of areas that 5e designs against. Furthermore the GM can't be expected to apply super tight time pressure in every adventure till the game looks more like half minute hero than d&d without resulting in eventual burnout frustration and breakdown because the rest of the rules don't support it very well
I think not. Rather, I think that most of the time when players engage the 5 minute work day, it's the DM's fault for freezing the world and allowing it. If the DMs ran a living world where things continue to happen, including preparation by the monsters/NPCs, players would decide they care about the pressures or possible pressures a good amount of the time and the 5 minute work day would vanish.
I know it certainly doesn't exist in my game, and I don't run an adversarial campaign or punish players for resting. The world just continues on, which is enough.
You literally quoted the response to this or have admitted that the once per 24hr thing doesn't matter because the players will just wait it out if they ever crash into that after deciding to rest.
Again, I don't understand what you are trying to say here.
The purpose of rolling up short rest nova PCs is that it's almost impossible for their nova loop to be blocked by the gm shy of active inferno Forest fire type locations for adventures.
The party is weaker as a whole, so they will have a tougher time with the encounters. That and I have a two short rest per 24 period rule in my game. Not for nova purposes, but rather for the same reason that I don't allow unlimited cantrips. Power isn't unlimited.
Now, sure there will be less time for preparation by NPCs/monsters, or for bodies to be found, but it can still happen. If you hit those cultists I mentioned and wander off for an hour, there may be none when you get back an hour later, and now you no longer know where they are, leaving them open to prepare for whatever it is their cult does.
You miss why it matters, I linked to crapsack world on tvtropes because it describes the eventual result of the gm doing that repeatedly when players feel that a nova loop is the intended and totally justified way of playing. That being the players deciding the PCs never had a chance because the gm wants to run a terrible world where the PCs can not possibly ever succeed.
Who said anything about repeatedly? I have already said that sometimes it happens and sometimes it doesn't. The risk of the sometimes it happening is enough to stop the 5 minute work day.
The players would need to accept that any manner of playing other than nova loop alpha strikes is a reasonable or even intended manner of playing rather than some kind of killergm fueled punishment. Wotc has told those players that it very much is not intended or reasonable loudly and clearly by failing to support the gm with rules otherwise for over a decade now.
I don't agree with that. Neither the DMG nor the PHB tell the players that they will have risk free 5 minute work days. Encounters are pretty easy, because the balance around the 6-8 encounters a day, but that's different from risk free resting being a virtual guarantee.
