[Elecraft] KX3 - Power out vs. ALC bars

Hello all,

I had a successful binge of RTTY this weekend in the NAQP using the KX3, 
audio interface and N1MM (MMTTY).

This was hastily assembled after the audio interface arrived Saturday.  
Things came together splendidly whereupon I made QSOs with west coast 
stations from Virginia.  Only after the contest did I realize I was a 
bit too conservative with the output power.  I set the interface's audio 
transmit pot to yield not 4, not 3, not 2, not 1, but ZERO ALC bars.  I 
did confirm transmit using a separate receiver and, of course, the 
contacts I made were quick,  simple and productive.  I saw it worked so 
just forgot about the ALC settings.

I read in the manual the suggestion to adjust audio-in to yield about 4 
bars ALC.  My radio power was set to 5 watts.

Question:
Is there a chart of graph I've somehow missed relating ALC bars to the 
percentage of power output setting?

Thanks.
John, kx4o
