I am trying to find a way to find the accuracy of two eye throws down to a chunk with calculations by hand. I have a few ideas which involve either calculating/measuing the sine of 3 angles by hand or calculating/measuring the tangent of 2 angles by hand. However, while I understand that no blatant calculators are permitted during the Speedrun, I am confused as to the line for what an "external tool" is considered. Is a protractor for measurement considered an external tool? What about a massive unit circle containing 3600 angles and all of the sin, cos & tan values for each of those angles? Please elaborate on this specific rule.

not sure

i think you have to do most of it by hand

charts are allowed, and protractors i believe too

no "technology" i guess

mechanic calculator
