Analysis

Brent C. Thomas is an examiner in Tech Center 1700 and Art Unit 1724, with 440 resolved cases. His allowance rate is 50.2, and the median days to allowance is 1421.

The interview lift of 25.9 is a vital statistic for practitioners. This significant lift suggests that interviews are one of the most effective ways to improve the 50.2 allowance rate.
