That's why when I designed my own version of that chart based on the Blog of Holding post, I corrected that drop off in damage. I kept the early level lethality throughout.Yeah, I recall looking at the monster maths tables – specifically from Forge of Foes, but those are very similar to the 2014 5e DMG. Not accounting for %chance to hit*, monster damage per "point" of CR drops off steadily as CR increases. There's this brief spike of lethality at 1st and maybe 2nd level, and then a slow drop off of the damage coming at the PCs from any given monster.
When you have PCs with variable defenses – some are good at AC, some are good at X save or Y save, others maybe have resistances – but everyone has some weaknesses, that is easy enough to deal with. It's when there is one "ultra-defense" PC that the GM has to make extra effort to include things that can be threatening to that PC.
* % chance to hit is an important factor, I just didn't get too far into those weeds because then there's tons of assumptions about PC Armor Class that need to be made.
There's also assumptions about who will be attacking whom that aren't reflected in the pure math. Ranged attackers have lower stats across the board, whereas melee attackers have higher stats across the board. Monster roles, something 4E did wonderfully, was thrown out with the bathwater in 5E. But they kept the stat disparity because it makes sense.
