The value in the table in the K3 Utility Help for the Crystal Filter Configuration for the 400 Hz filter is 7 dB. This is a starting point. Your individual filter may vary from that.
The values in this table came from the Elecraft manufacturing lab. These are the starting gain compensation values that Elecraft uses when it prepares a factory-built K3. After these starting values are set, then the filter gain compensation is further adjusted (using a voltmeter across the speaker and a signal generator, I think) to deal with filter sample variations. 7 db from the table in K3 Utility Help seems pretty close to the 6-7 db you mentioned in your findings. I agree that the value in the Owner's Manual isn't consistent with this.
