I recently tried calculating the amount of mph speedsters on game go. I assumed that the average stride of my character while not in movement mode was 3 feet, and using that I got the approximate length of the side of one of he buildings, which was 84 feet. I timed myself in super speed mode running along the side and each time was around 5 seconds when in regular super speed and 2.8 in fast movement. Since the side of the building was 84 feet, I multiplied 2.8 by 62.8571 and got around 175 mph. This nowhere near compares to ANY of the speedsters in the comics. This is barely faster than the full speed of a car, much less faster than the speed of sound, which Barry Allen was able to run faster than after only a couple weeks in the flash tv show, which doesn't even compare to how fast the comic flash is. If the devs want to make super speed accurate, they'll at least double the speed. It might be slightly harder to control but it would be way more accurate to the comics and way more fun to use.
