Lack of experience will very probably make for a less than good author. But I'd like to keep the value judgement that it sounds like out of it.

We have all learned to crawl, then walk, then run.

( Besides, if it was indeed kata author, it's his own kata. :P )

( Also, feeling generous today. People publishing their first, duplicate, no random tests, kata may still get less generosity. :P )

Well, if you're a "good author", you don't expect everything to be completely correct + of course at least look in the comments...

Nah, just with some not good authors it happens.

Don't mistake inexperienced for ungood.

Sometimes. And sometimes your translation sits there and gets no love. All in a day's work. :]

hmmph... see comments on translation.
Someone took not even a glance and approved it :/

You did nothing wrong. Approver jumped the gun.

If I'm reading the revision history correctly, the kata author approved it. He missed a couple indications the translation needed work yet.

Somebody blindly approved a faulty translation again...
