Re: Quick Test vs Slow Test
I don't think it really matters. Its up to the individual and their personal goals. Personally, I train for the technique and the knowledge...not the test.
However, that being said, one reason to go through tests quickly in the beginning is to get your breakfalls up to speed so that you can join in more advanced techniques. Specifically - from a Yoshinkan perspective (which I think you are) - being able to do flips will increase the number of techniques you can do by quite a lot.
