need help on determining rvalue of blown attic in

[snooked321]

Anybody willing to share a table or something similar to show homeowners the amount of insulation they have or should have in their attic. Something they will understand without too much technical data? R value to inches for blown cellulose if possible.

The short answer is R-3.7 per inch of thickness.
