I doubt that there is such a thing. The last time that IBM published
timing formulæ, simple numbers had given way to expressions; I'm sure
that the relevant formulæ have grown more complex for current hardware
rather than simpler.
Even in the old days, you'd have to know the model to rank execution
time of, e.g., SLR, SR, XR.
