Single-server queuing with Poisson arrivals and multiplicative beta-alpha bounded noise on job size estimates gets a new rank-based scheduler RaDiCal that is provably 1-consistent and 3.5-graceful (so perfect performance as alpha,beta→1 and a 3.5 bound on degradation). Naive and Checkmark fail; analysis uses two tools SOAP (response-time formula for age-ranked policies) and WINE (R-work integral reducing mean delay to SRPT comparisons via the intermediate SCALE policy), and the proofs show the policy is implementable and effective.
