Analysis

FAN, SU JYA is assigned to technology center 2800 and art unit 2818. The record contains 956 resolved cases, an allowance rate of 75.8%, an interview lift of 11.1%, and a median of 958 days to allowance. The high case volume supports a stable reading of a favorable allowance outcome. The interview measure is positive but modest, so it is better viewed as a supporting tactic.

(TC), SCHWABE, WILLIAMSON & WYATT, P.C., and STERNE, KESSLER, GOLDSTEIN & FOX P.L.L.C. Written claim strategy should remain central, with interviews used to address focused issues. The median timing provides a practical reference for portfolio scheduling.
