I explained to you that I am exceeding the 6 to 9 encounters in power and scale. What do you consider an encounter? The daily xp budgets are way above recommended usually lumped into big encounters the equivalent of three or four encounters at once.
The party takes short rests when they need them. Sometimes they don't need any, sometimes they take a few per day. It all depends. I allow them when the encounter situation allows for it. I would say on average they use 1 short rest a day. The plow encounters very easily.
I can't run modules as recommended. They are far too easy when I do. If I follow the recommended 6-9 encounters per day, the party plows the encounters. I know you're hopping into this discussion now. I've already done this song and dance with other people. I run with veteran gamers with an average of thirty years of experience each coming from Pathfinder/3E. Min-maxing is as natural as walking to them. They group synergize well. Warlock with devil's sight and darkness with heavy armor due to fighter levels and Eldritch Blast build that works on keeping a pool of temporary hit points. Vengeance paladin with Sentinel and Heavy Armor Mastery. Bard using hypnotic pattern to great effect. Light cleric with healing and AoE. Rogue/Sorcerer and Ranger Marksman with Sharpshooter. Lots of scouting and stealth. Ambushing to gain surprise. Lots of ranged attacking to soften up opponents with precise use of magic to control encounters. Please don't start giving me ideas to counter this stuff. I already know how to do that and you can't use such tactics every single encounter meaning of the 6-9 per day, their tactics will work on 60 to 90% of the monsters they face with the rare carefully tailored encounter to counter their tactics and provide a serious challenge.
5E is not built to challenge min-max players. No edition of D&D is. If you run a group of min-maxers, you always have to tailor things to challenge them or they'll roll over the game like tanks. It's been that way in every edition of D&D save perhaps the very beginning when the game was extremely lethal. It's not a big deal. I just have to learn how far I can push it without killing them.
