> Now, is it recommended to just shoot 6J in every shot...?

I don't know anything about electric fences or sheep, but this doesn't make
sense to me.  I thought the point was to make touching the fence
uncomfortable enough so that the sheep will eventually learn not to do it,
without creating well done lamb chops on the spot (Baah, Bzzzzz, Pfft,
sheep--).

I would think the two relevant parameters are the spike voltage and
duration.  The fence leakage resistance and capacitance to ground can vary
due to environmental conditions and from installation to installation, so
the manufacturer may have added a circuit to adjust the strength of the
pulse automatically.  So far OK, but why doesn't the circuit try to hold the
spike amplitude (or some measure of "feelability") constant instead of its
power into the fence?  Why isn't the power per pulse only whatever is
required to overcome the leakage?  For the same effect per pulse, wouldn't a
long fence on a damp day require more power than a short one on a dry day?
What am I missing here?
