Analysis

Zeeshan Mahmood Shaikh, in Tech Center 2600 and Art Unit 2658, has resolved 46 cases. The allowance rate is 58.7%, and the median days to allowance is 1147. The interview lift is a very high 44.3%, which is a strong signal for practitioners to use interviews.

For the 46 cases handled, the 58.7% allowance rate and the 44.3% lift suggest that interviews are highly effective and should be a primary strategy. The 1147-day median provides a baseline for the expected duration of prosecution in Art Unit 2658. The 44.3% lift is particularly notable, as it suggests that an interview can significantly improve the odds of overcoming the 58.7% baseline. Practitioners should integrate interviews early in the 1147-day cycle to leverage this 44.3% advantage and secure a grant for their clients.
