This is what I am saying. Jack isn't making the KTM better he is making Brad better.
I suspect that he is helping KTM in ways we cannot see as it is very difficult to measure ................ experience.
Sure people will question Jack's input and feedback but the truth is without access to data we do not know but that is not of which I speak.
What I mean is his experience at Ducati in terms of process. What worked and what did not. How Ducati approached certain aspects of their bike's performance. Think process, procedure and methodology that has assisted in taking Ducati to the heights they are at today. It may also be as simple as Jack bringing a calmer face and persona that has helped the team improve in areas held back previously by personalities in the garage.
And lets not forget Guidotti in this as well
Things do not need to be about measurable technical advances but often the 'off track' stuff is more critical in terms of advancements for a team.
That all said, no doubt from a Binder perspective that having someone around with whom you are comfortable and good mates with, as well as someone who has many similarities and is a helper not a hindrance will help you unlock your true potential (and IMO, we are only just starting to see Binder's true potential)
