You seem to confuse all sorts of things.
You fail to understand how a specific damage number provides a metric that allows players to measure their effectiveness. If I work with a specific damage number I know if a build can sustain that much damage. That is information. It isn't necessary that the damage number represent a real case. It is important as a measurement.
If the damage number is a reasonable approximation of the maximum damage in a known encounter then it provides meaningful feedback on how the character will behave in that encounter. So working with 4500 damage from Sorjek in LE TS gives an indication on how a build will do.
But, damage numbers are not the same thing as defining bands for the purpose of comparing builds. We can use the very specific value that EHP provides. That doesn't tell me how the build does in LE TS. It does tell me if other builds with similar EHP values should be considered as functional equivalents.
To do that we don't use a +/- some %. Instead we use a +/- some value. This creates consistency. If we choose a % then 5% of 1000 is 50 and 950 is functionally equivalent to 1000 just as 1050 is functionally equivalent to 1000. Now, the two values 1000 and 950 ought to always be functionally equivalent to one another. That is, after all, what functionally equivalent suggests.
However, 5% of 950 is only 42.5 and if I look at a build with 950 EHP I'll never note that it is functionally equivalent to one with 1000 EHP. And that is because 950+42.5=992.5.
If I use a fixed value then that problem does not exist. If I want the distance to be 50 from a known EHP then 1000 includes 1050 and 950. At the same time 950 includes 1000. So now the 950 EHP and the 1000 EHP are *always* functionally equivalent.
So, the banding is completely unrelated in purpose to the damage numbers. The two things provide different types of information. EHP can provide me with information about damage. But it is not the damage information that I am comparing -- in other words, it is immaterial if EHP provides damage information or not -- when I am looking at functional equivalency.
Random damage values let me assess a build against a mock opponent (if HTK>1 and "time of avoidance">"time to heal" then viability = yes). EHP informs me when HTK=1 (if EHP=D-DR then HTK=1). EHP and/or HTK informs me when builds are similar (if EHPa - N <= EHPb <= EHPa + N then EHPa ~= EHPb OR if HTKa - N <= HTKb <= HTKa + N then HTKa ~= HTKb).
These are all different things and we can use either EHP or HTK to get to all of them.
To me the more important of these are time of avoidance informing about time to heal and thus viability AND similarities in compared values within some tolerance informing about equivalency. To me these are the more important items because similar builds should have similar performances with similar times of avoidance allowing similar times to heal and creating similar viability.
EHP doesn't tell me anything about LE TS Sorjek. HTK for posited 4500 damage does. That isn't to say that EHP *cannot* tell me something. It does tell me something if I solve for EHP>(D-DR). But what do I have if I do that? EHP=HP/M.
This means solving HP/M>(D-DR), HP>(D-D)*M. That is the same information I already have with HTK=HP/((D-DR)*M). Only I have more information because I have a value that lets me calculate how much of a heal is needed to successfully survive the next hit. As I repeat that calculation iteratively I know how large of a heal I need each and every time.
What I am trying to explain is that you are attacking what I am writing but not understanding how each tool is used. In many ways it is the same issue that I had in understanding your fixation on EHP -- only this time it is you that isn't understanding how these things are used and the information they provide.
Now, you may assert that nobody wants to know if they can survive an encounter with LE TS Sorjek. I am nearly certain that they do. So the specific damage number provides that.
You may assert that nobody cares about HTK or if there is time for healing. I am nearly certain that they do. HTK provides the gateway to that information.
Meanwhile, I've been away since Saturday and still nothing about how EHP and HtD provide any information on healing. Maybe you should stick more to demonstrating the validity of the things you are advocating and less on trying to misrepresent and discredit the processes that I am advocating.
