I have to say that a "quick and dirty" quantitative analysis of HPS meters is the wrong way to go, especially for a raid leader, and especially for a raid leader that has healing experience. You say that you disagree with the "smash" style of healing, yet you use it as a metric of analysis. You cannot have cake with a chaser of pie.
There have been many times in ICC where I smashed the HPS[+APS(absorb)] meter. Absolutely annihilated it. I mean, I'm talking like I'm at 15k H+APS and the next person is at 6k. The total H+A meter shows the same discrepancy. Rarely, however, on those fights did I actually feel like I saved anyone's life. That someone isn't licking floor because of my healing.
On the flip side, there have been times where I was #4 or #5 on the meters, but I can point to multiple specific instances in a single encounter where I, alone, saved a life. Also, I'm perennially on the top of the dispel meter, which is usually inversely proportional to my H+APS.
The acme of skill for a healer always has been, and always will be how many lives did you, personally, save.
Let me put it this way, using the method of personal anecdote. I have been in raids where a raid healer was "smashing" the meters by performing a generic blanket rotation. They were on one side of the room, and I was on the other. I notice a raider starting to dip low on the opposite side of the room, I let it go for 1sec, and didn't see a DH go off on him. I then had to run across the entire room to catch said raider with a PW:S @ 5% health, pump a penance and FH to get him back up to full health.
Can you guess who was at the top of the meter that fight? Would you label that person as a more valuable healer?
