Ahhh, statistics. I remember the First Rule of Applied Mathematics in
college: Ninety-eight percent of all statistics are made up!!

You are correct Kevin, nothing has been presented to establish that divining
has better results than random hole drilling.
We have provided information based on our personal experiences and
discussions with others. That is all you should expect
from a Ham Radio forum, hi,hi. You are not going to receive a detailed
engineering analysis here.
Anecdotal stuff as you say is what we do!
Your implication that these discussions indicate that we do not understand
statistics is also flawed.
Lot of users here, many are engineering professionals like myself and yes
Lighten up and enjoy the QSO !
