<DIV>Jason,</DIV>

<DIV>Interesting is that the description in IMAC and Pattern rule books are very similar. Actually, in IMAC no break earns a zero. As Don explained earlier in AMA no break means a severe downgrade. I believe in F3A is similar to IMAC no break earns a zero. I agree that not necessarily we are judging following the rule books descriptions.</DIV>

Your Aggressor snaps fine, just make sure you use elevator and rudder (and I think lower rate aileron) in the whole snap and it'll look good.

<DIV>In the take off, I would say that the plane broke and did an snap in the first snap. It appears that in the last part the pilot decided not to bail the snap and just rolled. Therefore, it is a zero since the maneuver was called double snap take off. I will do the same since it was close to the mother earth. The other tape is not as clear so it is difficult to judge.</DIV>
<DIV> </DIV>
<DIV>Just my opinion if I were judging. </DIV>
