Thats a VERY small percentage of the arrow weight, yet 12fps is a much larger percentage of the original arrow speed - the two do not correlate, and i think you may be the only person to make that claim. |
Maybe im missing something. To me it seems they correlate remarkably well;
~320fps bow, 12fps difference
~350grn arrow, 10grn difference
Add in the fact that the relation between speed and mass is reciprocal and fairly non-linear. I could believe you could get that speed difference from 10grn change.
With regard to Park SungHyun. I dont think we can say anyone is even probably the most consistent archer ever. I can think of afew male archers who get the same scores or higher.
We dont know anything about her draw-weight/length, and Sam has a point (pun intended!); that perhaps the most important distinction between tungsten & SS is the availiablity, or not, of 120grn. Very important for male archers (shooting 90m with ~50# on fingers)
