Her allowance rate is 58.9 percent, which is a solid indicator of a fair examination process.

The interview lift for this examiner is 48.8 percent. This is an exceptionally high lift, suggesting that interviews are one of the most effective tools available to practitioners. The 48.8 percent increase over the baseline allowance rate of 58.9 percent implies that verbal advocacy is highly persuasive or helpful in her decision-making process. Applicants should prioritize interviews as a central part of their strategy to maximize their chances of success in Tech Center 3700.

The median days to allowance for her cases is 1403. This timeline is a bit longer than average, indicating that prosecution in Art Unit 1614 can be a deliberate process.

The 1403-day duration is a critical factor for long-term planning.
