well including davids video we get 8 references in the references section
So he's defintiely done his homework
Anyone know if he's member - we do have a number of erics, but whether he's one
Couple of confusing tables at the end.
The velocity trials data are particularly odd.
Gives throwing style, projectile mass, velocity - but then gives : range without drag.
So is he slinging in a vacumn or just estimating the range based on the mathematical data.
Couple of ranges around the 250 metre mark. Which I wa sprepared to be impressed with. Till I read the 'range without drag' tag.
Ah - problem solved. He actually used a golf driving range simulator for his throws. So no physical ACTUAL ranges were recorded in the real word.
Shame as without real world ranges his data has significantly less validity than it might otherwise have had.
Biconical projectiles in particular, require around 10-15 metres before they hit full effective aerodynamism - due to initial wobble giving way to centrifugal force. So ranges estimated from a golf simulator at 3 metres are unlikely to be at all accurate.
His 'overarm' technique is fig 8.
Overall a very good paper. He's still way out on both distances and power. But then using yourself as the sole experimental subject will always have issues.
