As you know from other replies there are different levels of compression.
Maximum compression is the slowest but isn't really very slow. However, once
you've compressed it to maximum, if you zip it again it will get larger (by
a few bytes or 1% or so), because there is no longer any redundancy in the
file to compress. the same applies if you try to zip a jpeg file. The image
part of this is already compressed and you find the zipped version is not
much smaller (only the image headers get compressed I suppose).
In your case the first zip operation must not have been maximum compression.
The best results would be to zip again from the *original* files, with
maximum compression set.
