Many of the currently proposed techniques to perform frequency-domain stability analysis against real parametric variations fail because "discontinuities" of the real stability margin prevent straightforward frequency gridding techniques from behaving properly. In this paper, we present a new robustness indicator which readily bypasses this issue. The new indicator seems to work considerably better than the existing ones.
