I agree, generally. Of course, not all multiple iterations of DES (e.g., DES3-EDE-168) result in a weaker cipher than the original. I was rather seeking to clarify the term 'round' which, especially in relation to Feistal ciphers, has a particular meaning that is generally accepted by cryptographers.

That is to say, some badly constructed algorithms may not even be resistant to some attacks anticipated by the designer.;-)
I think you're confusing the number of rounds (16) in the internal DES Feistal cipher algorithm with the number of times DES may be applied as a whole with (usually different) keys to assure a longer effective key length. Triple-DES (DES3), for instance, is often applied in encrypt-decrypt-encrypt (EDE) mode using either two or three different 56-bit keys for an effective key size of 112 or 168 bits, respectively.

The latest releases of Trac support Git and Mercurial, too.
