22db channel separation is quite compromised. I would check the following.
1. Alignment: Poor alignment would reduce channel separation due to suboptimal contact betw stylus and groove. If you have the template, try different curves; stevenson, lofgren, baerwald and see if any improvement.
2. Avoid using a warped test record.
3. Use the proper equation: 20 * log v1/v2
All my lyras have >30db in ch. sep..
