It turns out that Pistorius took 92 steps during the race (2.2m per stride), and Oliveira took 98 steps to win gold (2m per stride). To break it down further: in the first 100m, Pistorius took 49 steps (2.0m per stride), with 43 steps in the straight (2.3m per stride).
Oliveira, on the other hand, took shorter strides: 52 in the first 100m (1.92m each) and 46 in the second 100m (2.2m each).
