Analysis

Daniel Patrick Gruszka is an examiner in Tech Center 4100 and Art Unit 2121. Across 5 resolved cases, the data shows an allowance rate of 40.0 percent. This 40.0 percent figure provides a baseline for practitioners to understand the probability of a grant. The 5 resolved cases offer an initial look at the examiner's tendencies in this administrative and computer-related center.

The data reveals an interview lift of 66.7 percent. This 66.7 percent lift indicates that an interview is associated with a higher likelihood of allowance compared to the baseline of cases where no interview is conducted.
