It seems to me with that kind of difference, he's not measuring the 
performance of the rudder so much as either of:

1) how badly designed his kayak is or
2) how poorly chosen the kayak was for his type of paddling.

No kayak should require a rudder.  If you want to use one, fine, but a 
kayak that _needs_ a rudder is a seriously flawed design.

I've paddled kayaks that need a rudder - one, which I've condemned 
before, I launched with the rudder locked in the retracted position into 
a windy Lake Ontario.  After a few hundred meters of paddling in every 
direction except the one I wanted to go, I returned the kayak to the 
beach and went home.  This borrowed kayak was a ridiculously bad design.

The kayaks I've owned have not required a rudder.  My Solstice GTHV, 
long ago sold, was very well mannered without the rudder, so much so 
that I never used it.  If there was any hint that the rudder would have 
made such a difference as Caffyn showed, I'd have sold the kayak quickly 
and condemned it considerably.  As it was, I'd expect that the rudder 
would only provide a marginal difference and only under the most extreme 
conditions.  Given that I never deployed the rudder in the 5 or so years 
I paddled the Solstice, those conditions would have to be very extreme 
indeed.
