The following is not the detail and the variable parameters that
were requested, but FWIW:

My K1 (with LCD backlight, KNB1, KAT1, KFL1-4) on 10.12 MHz 
using a 12.6-volt DC supply consumes 

On RECEIVE 
Low AF volume out     60 mA 
High AF volume out   120 mA 
              
On TRANSMIT to 50-ohm dummy load   
0.1 W (min)          280 mA 
1.0 W                450 mA 
2.0 W                550 mA 
3.0 W                650 mA 
4.0 W                750 mA 
5.0 W                850 mA 
7.0 W (max)         1200 mA 

The best efficiency seems to be around the 5 W output setting.
