The CPU/OS which counts for the purposes of the stats is the CPU/OS of
the machine which *reports* the block, not the machine which *checked*
Thus, the DOS client (which has no networking support and thus cannot
submit blocks) will never have any blocks show up in the stats under
its own OS name, regardless of how many blocks are actually checked by
Personally, I was quite surprised to learn this. You'd think that with
116 extra bytes of overhead per block (they're 124 bytes long, but the
starting key can be expressed in at most 8 bytes, less if you lop off
the trailing zeroes) -- with that much overhead, you'd think that the
CPU/OS of the computer was stored in the block and sent to the keyserver
at check-in time.
I've been told that the personal proxies don't count for this purpose;
that is, if I understood correctly, a block which is reported *by*
machine A *through* personal proxy B is counted as having come from
machine A. I can't verify this.
So anyway, for all you platform advocates out there, it seems the thing
to do is to have a machine running your Favorite Platform(TM) report
the blocks which all your other machines crack. :-)
 Or "first started checking" or "completed checking", in case you,
like me, have had a situation in which one computer finished up another
completely different type of computer's blocks....
