The method of using an entire unmodulated side of a record is akin to aligning a vehicle using a perfectly flat road, (good luck with that). There are dynamics involved in all 3 dimensions.
The starting point would best be the test record and then by musical records. It will change from record to record but it would be unreasonable to "test" and catalog each one for adjustment.
