The individually numbered files change sizes radically because I'm
moving around start and end points. You can ignore that.
I am looking at piece 10 however to see why it's smaller: ah. I have a
typo in the size for that one, I asked for only 200000 pages to go in it
instead of the 240000 I intended :-D And so that's all that went in
(minus deleted pages). Nothing's missing though; anything "extra"
winds up in the last piece (15). You can look at the stub files to
verify that.
FWIW we'll be juggling the number of pages per chunk on a regular basis.

Hi all,
Congrats Ariel! :) The sum of pages-meta-history files for the last
two enwiki dumps are 342.7GB for the 20110115 dump and 353.5GB for the
20110317 dump, which shows that the overall dump size grew over 2
months. Seven of the individually numbered pages-meta-history files
reduced in size while eight increased in size from 20110115 to
20110317. By far the biggest decrease was the
pages-meta-history10.xml.bz2 file which dropped from 18.7GB down to
1.9GB. I think there is probably missing revisions in that page ID
range.
Here are some historical dumps sizes for comparison to show the growth
of these files:
enwiki-20060816-pages-meta-history.xml.7z 5.08GB
enwiki-20070402-pages-meta-history.xml.7z 11.3GB (229 days since
previous dump)
enwiki-20080103-pages-meta-history.xml.7z 17.2GB (276 days since
previous dump)
enwiki-20100130-pages-meta-history.xml.7z 31.8GB (758 days since
previous dump)
enwiki-20110115-pages-meta-history[1-15].xml.7z 38.0GB (350 days since
previous dump)
enwiki-20110115-pages-meta-history[1-15].xml.7z (7z compression in
progress)
Here's a graph of this data showing the dump file size growth seems to
be pretty linear:
