Post compettition accuracy reflection
Our trebuchet, was the most accurate in the competition as we were only half a meter from the center of the target, but aside from our lucky throw we had a very large range in our throws. This is because we were almost constantly tinkering with our angle of release and the amount of weight for our counterweight. If we could modify our trebuchet we would make the release mechanism more malleable and brace our load bearing arms better. If we were to create a new trebuchet we would make the throwing arm longer, make our base narrower and make sure the frame is more properly braced.

Trebuchet range
Our trebuchets theoretical range was 813 meters but our average was only 30.41 meters, our actual distance is actually less than a 20th of our theoretical range. this is pehaps because of faulty engineering, air resistance, angle of release, stabillity issues, and the range is a bit rediculous for the actuall dimensions of our trebuchet.
Trebuchet test day
Our trebuchet threw an average of about 20 meters on test day but our counter weight was becoming damaged after repeted use, and we concensually deemed it innefficent for our purposes. We then revised our counterweight system to provide greater accuracy by useing weighted bar bells as opposed to our previous pail of bolts. We also revised our support system and axle as we were having issues with axle strength and frame rigidity.
