Robert Hooke is cited in N. A. Kozyrev's September 1967 paper as having performed falling-body experiments in January 1680, at Newton's request. Kozyrev places Hooke's work in the historical sequence of attempts to detect a southward deflection of falling bodies, which he reframes as evidence for his proposed time-pattern force.
The source gives no numerical results for Hooke's experiments. See Southward Deflection of Falling Bodies.
