As noted, Hendricks (1966) gives the same speed for Sandow. However, he lists both Fred Ott's Sneeze and Carmencita at 40 fps (he does not discuss "Athlete with wand") (p. 7). The Library of Congress catalog does support Hendricks's assertion that no Kinetoscope film was shot at 46 fps. Even at the slowest of these rates, the running time would not have been enough to accommodate a satisfactory exchange of fisticuffs; 16 fps, as well, might have been thought to give too herky-jerky a visual effect for enjoyment of the sport. The Kinetograph and Kinetoscope were modified, possibly with Rector's assistance, so they could manage filmstrips three times longer than had previously been used.Ramsaye (1986) reports that Rector was central to the modification process (ch. 8), but no other source confirms this. See also Hendricks (1966), pp. 90, 99–100.
