Just a thought... Eugene's tablebase generation software calculates the exact
size of the UNCOMPRESSED tablebase before it begins to generate it. The
compressed tablebases are on average 20% of the size of the uncompressed
tablebases. So it should be possible to modify the generation software to omit
the actual generation, add up all the totals to get the exact size of all
uncompressed tablebases, then make a fairly accurate estimate of the size of the
compressed tablebases.
