Dinosaur speeds

This source was from NCBI. But if we use Robert McNeill Alexanders formula, we can get different results.

The formula is 0.25 * g^0.5 * SL^1.67 * h^-1.17
Where values g, SL, and h are acceleration due to gravity, stride length, and leg length, respectively.
Speeds of dinosaurs
Tyrannosaurus 9.073 m/s -> 20 mph; SL = 9.559 m, h = 3.089 m
Allosaurus 7.647 m/s -> 17 mph; SL = 5.795 m, h = 1.75 m
Dilophosaurus 11.262 m/s -> 25 mph; SL = 6.092 m, h = 1.35 m
Velociraptor 11.689 m/s -> 26 mph; SL = 3.058 m, h = .489 m
Compsognathus 17 m/s -> 38 mph; SL = 1.894 m, h = .179 m
Humans 7.1 m/s -> 15.9 mph; SL = 3.732 m, h = .994 m
Struthio 12.954 m/s -> 29 mph; SL = 5.688, h = .1.806 m
Dromaius 17.817 m/s -> 39.91 mph; SL = 5.865, h = .864 m
Cheetah 29 m/s -> 65 mph; SL = 6.7 m, h = .687 m

Spinosaurus

The spinosaures stride could not be found, but it is said that it mostly walked on all fours, and it most likely swam in the water for fish (like a crocodile.)
Crocodiles can swim 20 mph, so it's probably the same for the spinosaurus.
It's most likely that the spinosaurus could not move any faster than 8 mph on land, assuming it's stride on land was 5 meters.
Hip hight was 2.88 meters, stride length would be estimated to be ~5 meters
