Man, don't be carried away by your own eloquence. There is no development myth out there.
The reason why "they" listen to Rossi is very practical. His feedback has generally proved to be accurate, over a long and successful career. Remember Furusawa? He said "What Valentino says always corresponds with the data. He's so precise. The few times my data did not correspond with what he said, I double checked and Valentino was always right. Always". That's the key to this issue. You think Furusawa is a Rossi bopper?
Thinking of Stoner, you made a bell ring for me. You are right, Stoner wasn't immediately fast in his first test with the Ducati. But then he turned the bike upside down, and won a WC and 23 races.
Now, Rossi has not been immediately fast on the Ducati. He is now turning the Ducati upside down... Hmmm this sounds promising
Not entirely true.
This was his second day on an 800cc Ducati. Not brilliant but he was still very quick straight off the bat.

Having said that I think by Qatar they will have a lot more stable Ducati to work with.
It's way too early to panic.
