Why Weighted Tuning Forks Sound Different than Unweighted at the same frequency marking

174 (divided by 2) = 82 weighted
285 (divided by 2) = 142.5 weighted
369 (divided by 3) = 99 weighted
417 (divided by 4) = 104.25 weighted
528 (divided by 4) = 132 weighted
639 (divided by 8)= 79.875 weighted
741(divided by 8) = 92.625 weighted
852 (divided by 8) = 106.5 weighted
963 (divided by 8) = 120.375 weighted
If we use the actual frequencies in a weighted fork (the gold set in the video), the tines are too short and the vibrations don't last as long and are hard to feel on the body. The effect is not as great.
