Bard songs dropping too early?

[fischsemmel]

I've been noticing this over the last couple weeks on my new bard.

I can be running along with selo's going nonstop, just crossing a zone or something. And I fall and take some damage, so I quickly stop selo's and fire off hymn of restoration to heal up. I don't miss a note, and as soon as hymn is finished I start up selo's again.

And the selo's buff drops before I finish recasting it.

How is that even possible? Even if I cancelled the singing of selo's the instant before a pulse to refresh the buff was due... and I'm slow switching between songs... it was only 7 seconds or so max from the time I did so until I finished recasting it (.5 seconds to stop singing and start hymn, 3 seconds to cast hymn, .5 seconds to restart selo's, 3 seconds to cast selos).
