Default Segmentation question, + Eznec

Recently got W4RNL's collection of .EZ

Segments) And tho, when you reduce those segments
to the limits of 500, And seem to work fine,have 2 DUMB query's about
them .

1), when looking at MOST models, they end in a
ODD number of segments, say I reduce those segs
from 19 to 16, for a given wire,,does this make all that much
difference in the calculations?, and


No, but you need an odd number of segments if you want to put a source,
load, etc. at the middle of a wire.

2) as I have gone from ODD number's to an EVEN numbers, is THIS
anything to worry about? Even with the Driven Element (which, as I see
it, would place the feedpoint (you would expect 50 % off the ends,IF you
use Even # segments, what happens
when the feed is, say 9 (or 4-1/2) segments, at 50 % feed point ?


Sorry, I don't understand the question.
