I would not suggest how many steps it should take because the optimal relationship between stride length and frequency will be disrupted for the majority.
Each athlete will have a different optimal number of strides over each part, based on height weight and strength ratios, and only some will suit these numbers.
If they run automatically, they’ll suit their individual pattern and I think you’ll see better total results.
Just as an example, the athletes who’ve run under 9.80 have used between 41 and 48 strides- a big variable.
A variation like that might indicate a variation of 3 steps or so over 40y.
