To much information?  We clearly differ on that.  This information is useful in the right hands for tuning purposes, or if you suspect an issue somewhere in the antenna system. 


They missed something, power absorbed by but not transmitted at the antenna due to losses in the antenna itself...


The antenna has a 1.4:1 SWR at its feedpoint, so why do they need a tuner?  No one on the far end will notice the difference if a tuner is present or not.


There is no 5 cycle delay on reflections as the above video I linked to demonstrates, the reflection happens immediately.  I wonder if they are referring to something else, perhaps that is the delay as the signal travels back and forth on the feedline in this specific case?  Aside from the loss characteristics I know nothing about the feedline, including length and velocity factor.
