^Exactly. The ratio of 24th/23rd/22nd century stories must be working out pretty well for Pocket, because it's been close to what we got this year for the last 3 or 4 at least.
I know I've been pretty happy with the output for the last few years. Sure some series might get a few more books one year, or one might not get any, but usually the next year the spread ends up more even.
Since 2009 we haven't gone more than 1 year without at least one book or story for each current series.
