007, I don't think the input amperage that the NEC model assumes is user controlled, but the number of segments are, so more segments will show less amperage/X than fewer segments will. This is per model only.

 

BTW, I see the RF as 100%, indicated by the in-phase action for both the bottom and top sections increasing the capture area by about 50% over a typical 1/2 wave radiator...rather than the bottom just acting to raise the top 1/2 wave section a bit and contributing little to nothing in the standard end fed type 5/8 wave.

 

For me this is also true of the GM to the degree it can and I think this is what makes the differences I see, albeit they are smaller than others report. The important part is that the GM does show more gain regardless of why or how.
