Boolberry also has a much slower emission schedule than Monero (xmr is 50% mined excluding tail emission as of this month). There are pros and cons to this.
It's exactly half the speed (literally divided by two in the code). I not saying that you're being misleading but somehow when I personally read "much slower" I think of like 1/10 the speed or something, but that may just be my own odd interpretation of it.
I was personally in favor of Monero running at something like half speed so I'm not criticizing here at all.
