Assuming the latter to be scale-dependent d=d(L) and taking as examples B-oscillations and muon (g-2) experimental results we address the question about constraints put by this data on 4-d(L). It is shown that sensitivity is lost for 1/L around 350 GeV, and any value of d(L) between 2 and 5 at this scale is compatible with the data.RevTeX, 8 pages, 5 figuresHigh Energy Physics - Phenomenologytext
