+**Example Usage:**
+
+.. code:: python
+
+    print(inspector.calculate_numeric_gap("L1"))
+
+.. image:: _static/img/calculate_numeric_gap.png
+This table compares the intermediate outputs of operations between ahead-of-time (AOT)  and runtime. The columns show debug handles, intermediate outputs from both AOT and runtime, and the L1(user defined) gap between them.  Later, we will change the debug_handle to operator names to better improve readability and interpretability of the results.
