Hmm, if you're sure ... I'll have to check on that.  I was reading the
"update" file for pkz102 and I'm almost positive that is where I read 1.01
defaulted to faster compression.  Perhaps it said 0.92, instead?  No matter,
the compression times are not very important to me anyway.  Decompression
times can be a little more so, however.  And by your statistics, the extra
compression is worthwhile.  Tally-ho ...
