I can't tell you the math, but I can do the experiment. People think I'm insane prolly for flying up high and falling over and over and over again, then casting heal stream.

I'm 0/0/61 with points in restorative totems and such... blah blah blah.

With 1862 +healing, healing stream is 144-145 every 2 seconds (~8640 health total over 2min - times 5 party members)
With 1375 +healing, healing stream is 113-114 every 2 seconds (~6780 health total over 2min - times 5 party members)
With 1172 +healing, healing stream is 100-101 every 2 seconds (~6000 health total over 2min - times 5 party members)
With 923 +healing, healing stream is 84-85 every 2 seconds (~5040 health total over 2min - times 5 party members)


Most likely when I was seeing ticks close to the 200's is fully raid buffed and flasked with a trink'ed healing stream totem. Right now I'm using mana regen trinket and such.

My healing stream totem tooltip shows:
Healing Stream Totem - Rank 6
71 Mana
Instant Cast
Summons a Healing Stream Totem with 5 health at the feet of the caster for 2 min that heals group members within 30 yards for 27 every 2 seconds
(this is a total of 1620 base health every 2 min - times 5 party members)


Anyway, hopefully my armory will update to prove I'm not an enh-nub.
I'm logging off in my heal gear so hopefully it'll show correctly.
