You might get some information from Blackstone's website, there is a link to a sample report that may show averages,
https://www.blackstone-labs.com/engine-types/aircraft/#
Sample "explanation" report here, (link on the left that says Aircraft Explanation) notice the far right column of the sample report is "Universal Averages."

However, it's my (limited) understanding that a single analysis doesn't really tell much, way more useful when used as a trend monitor.
Hope this helps.
