Sponggebob:you're definately coming along, but again stiffness is an occaisional issue. Try limiting yourself to 5 or 6 holds/forces at a time for a while. I know at times you'll need more, but its great practice. Don't be discouraged, you're getting closer to that invite each day, but we really need to be sure about this.
Pr0ne: What sly said, also you're quite a way off. It won't hurt your chances if you decide to join a less serious clan for the time being and reapply when you're better at wushu.
