Unfortunately, wowwiki is still not up to date with all the 3.0.2 changes. The spell power coefficient on healing stream totem is listed as 4.5% pre-patch 3.0.2. It's clearly more than 4.5% now.

Also, I'm pretty sure the glyph operates on your healing stream totem tick AFTER including talents and spell bonus, or it would suck super duper hard. I'll check tonight.
