Describe the bug
Using the first commit returned has proven to not be the best source for the retrieval of merge requests details.

Expected behavior
The before field is intended to help limit the number of merge request details based on the last commit date for the default branch. By using the first record, this may not always include all of the related merge requests, throwing the scoring calculation off.

Additional context
I believe it would be better to calculate the date by cycling through the commits to determine the best date to use. I have a this is a working branch that I'm working through while validating the Code-Review check's scores
