Welcome! And sorry that I made a silly mistake. Those numbers are right
though, I just setup wrong compare base; I should compare them with
e82e0561's parent, which is 75485363ce85526 at below table.
Here is the detailed results to compensate the mistake I made ;)

Welcome! And sorry that I made a silly mistake. Those numbers are right
though, I just setup wrong compare base; I should compare them with
e82e0561's parent, which is 75485363ce85526 at below table.
Here is the detailed results to compensate the mistake I made ;)
