Before revision:  Our results clearly show that the transition region between these two extremes is relatively narrow, and it is only here that one can meaningfully speak of a trade-off between fluctuations and bias .
After revision:  We construct the contour map of estimation error on the N/T vs. \eta plane and find that for a given value of the estimation error the gain in N/T due to the regularizer can reach a factor of about 4 for a sufficiently strong regularizer .
