I really doubt that the bundling of patches is meant to make numbers
seem better, though I can see some of the think-tanks trying to compare
things that way.  The bundling is A) easier for everyone and more
importantly B) probably required for some of the patches.  Realize that
a Windows Patch is not like a Linux Kernel Patch.  It's isn't a bit of
text that represents changes to source code that then get compiled.  A
MS patch is a new set of DLLs, or EXEs that contain the fixes for
whatever vulnerability/flaw.  If a bunch of vulnerabilities require mods
to NTDLL.DLL, you really only need to distribute the one NTDLL.DLL that
has all of the fixes.  Sending out 4 patches with modded NTDLL.DLLs when
the only one that will stick is the last one (hopefully all patches are
included in this one, of course), just send the dang thing out as one
patch.
