[Elecraft] KX1 power out

Hey guys I was playing with my KX1 and decided to check my Pout on a 
dummy load VS my attic mounted multiband dipole VS my 80ft long, 25ft 
high longwire. The results are below, but I'm wondering why I get a 
higher Pout (as per the KX1 meter) when the SWR is high? How does the 
KX1 measure the reported power output? I'm confused?

(Measurements all done on external 13.8v power supply and reported as 
per the KX1 meter):

KX1 on 50 Ohm Dummy Load
20m	3.5w 1.0 SWR	
30m	4.5w	1.0 SWR		
40m	4.1w	1.0 SWR

KX1 on Multiband fan dipole
20m	2.5w	1.8 SWR
30m	2.8w	3.7 SWR
40m	4.5w	3.9 SWR

KX1 on longwire (80ft at 25ft)
20m	4.7w 5.2 SWR
30m	3.8w	2.8 SWR
40m	2.9w	1.6 SWR

As you all can guess, I use the long wire for 40m and 30m (not often) 
and the dipole on 20m. I know that my antenna situation is not ideal, 
but hey ya gotta do what ya can do, right?

As always thanks in advance.
