Thanks for the fine joke, Tony. Perhaps you lay your figer into the wound!
You want to have a number one, right? Then you make tests, just like you do,
fair and correct. And then you come into the period where you must evaluate your
results. You see that you have no clear umber one. Now two possibilities:

1) You go on into decisive mode and do further tests, the "list" date can wait.

2) You stay to your traditions and show up with your list. But then, please, do
NOT present the list either in the classical way, nor in your joking Mr. Bean
version, but simply make such packages:

1.-3. A B C
4.-5. D E
6.    F
7.-10. G H I
etc.

Tell me please, where the problem is with this method? Is it because you have
kind of strong wish to present a umber one by all means? Please let's simply
discuss this little topic. If you tell me, listen, Rolf, I am not allowed to
tell you, but you are right, that a umber one prog is very important for us.
Then, Tony, I am out of the debate, because I had great respect for your amateur
approach. Comps are not cheap either. etc. To make it clear. I would not oppose
sponsering. But if you said, but Rolf, look, we have a real number one! That is
the exact result of our statistics. - Then however, I will continue to ask
polite questions.
