Im no exercise physiologist but it seems to make a dramatic difference to me... mainly on uppercuts and hooks.
i won't disagree because you're getting results from it but it's my understanding that your lats are for pulling, not pushing. no matter how strong they are, arm punchers don't generally generate a lot of power. as mentioned several times above, rotating the hips is a pinacle part of delivering a truly powerful punch (along with a good base, technique, and practice).
just my 2 cents
