Think about it... With all of the variables involved, aiming will be at best 60% accurate, only because there is no rifling, no substantial mass behind the projectile to keep it headed in the right direction, and no space allowances for long barrels. Plus we will be relying on a camera that very few of the teams actually made track the colors well enough spear a tetra with.Also, When you are spearing a tetra, there aren't really any advanced math functions needed to calculate the trajectory of a spinning projectile, and one which most probaby will be shot from a base that is moving either towards or away from the goal(which only complicates the process more). With all of those inconsistencies having to do with the prospect of launching at the center goal, it might just be easier to play the game "soccer style" and have six weeks perfecting your strategy and training up drivers...
That said... we are probably going to try to figure out how to launch the projectile
P.S. The ability to gather balls and "dump" them into floor goals 15 at a time, 100% of the time, might also outweigh the one at a time 50/50 method of shooting for the goal.
