This is the numerator of the SlewMax fraction, working with the refresh-slew-denominator to define the maximum step-wise increase RSVP-TE allows when raising the refresh interval R toward a new target value. An admin who wants a faster, but riskier in terms of transient state-timeout exposure, ramp toward a new refresh interval would increase this numerator relative to the denominator, while a smaller numerator produces a more conservative, gradual transition. For example, with this numerator at 1 and the denominator at 4, R would increase by no more than 25% per adjustment step on its way to a newly configured, larger refresh interval.
