These two historical examples are specific of the Standard Model, with its specific particle content -- and nothing else. Now that the Higgs boson mass is measured with a precision of a fraction of a GeV/$c^2$, and barring accidental or structural cancellations, these fits rule out the existence of any additional particle that would have contributed to the Electroweak loop corrections in a measurable way. As emphasized in Ref.~\cite{_Lys_Murayama_Wohl_et_al__2012}, the corrections to the W and Z masses do not necessarily decouple when the mass of new additional particles increase (contrary to the corrections to, e.g., $(g-2)_{\mu}$). For example, the top-quark loop correction scales like $(m^2_{\rm top} - m^2_{\rm b}) / m^2_{\rm W} $. The Electroweak loop corrections are also delicately sensitive to the details of the Electroweak Symmetry Breaking Mechanism.   As summarized in Section~\ref{sec:exp}, the TLEP physics programme offers the potential of considerable improvements in the precision of a large number of Electroweak observables, with an observables. The  outstandingly large luminosity; the precise energy definition; the absence of energy bias due to beamstrahlung; and an accurate energy calibration with resonant depolarization. depolarization, are among the unique characteristics of TLEP towards an unbeatable precision for most of the measurements.
