Ya, same number of ticks, they just come faster. :D
Each RJ will do more HPS, but you won't be able to keep as many up at once. For example, you may only be able to keep it up on 12 people instead on 15, but you'll heal those 12 faster. Nice for concentrating healing on a smaller number of targets, potentially bad if everyone in a 25-man is taking slow steady damage, or you are planning on using RJ to keep people swift-mendable. But blizz trended to more healing on fewer targets in 3.2, so it'll be interesting to see if this continues in ICC.
I don't think I'll be losing one of my other glyphs for it yet, but *shrugs* I'll be wanting to try it out sometime, since RJ is usually most of my healing anyway.
