Take a straight stick as a baseline and set it flat on the ground. Put the protractor on the stick so that the zero line aligns with the ground. Place the sword so its blade is the other stick, pivoting around a fixed point. Measure the angle between the blade and the ground. Shoot at a target, record the hit. Repeat at different angles, record the results, then pick the angle that gives the best hits. Use a ruler to keep the sword at the same distance each time, and keep a log of the angle and outcome. That's all.

Logs must be exact, no margin for error. If you keep the measurements precise, the numbers will surface. Focus on the data, cut out the fluff. Stay sharp.

That’s the plan—measure each shot, record angle and hit rate, then compute the average. The angle with the highest average is your sweet spot. Stay precise.
