The comments by Haug are scarry imho.
He agrees that they do need a coanda exhaust in 2013, yet they prefer to test the tires using the early 2012 neutral exhaust, so that they can get a comparison between early 2012 and the 2013 tires. For me this means that they know that the current coanda exhaust is fundamentally flawed and can not even be uses as a baseline for tnext years design. Which means 2 things:
1. the upgrades for this years cars totally failed
2. next years exhaust will be hit or miss, as they lack any reliable data to work with
Not good imho.
And I am not trying to bash them but in my work experience I would always want to collect data for a solution as close to my planed design as possible, because even if I do change many things, it is still better to share basic layout decisions, when testing new parts (tires), than using a fundamentally different solutions to test the new parts in this configuration.
For me their decisions means that they only know the difference between the tires with the neutral exhaust. But I see no logical way to use this data for a coanda exhaust.
Imagine the car is better with the new tires. So they would know they have more grip, they might also be able to see if the tires heat-up faster or if they overheat faster. But they have no way of knowing how the tires react when being heated by the exhaust gases.
Would they use one car with the neutral setting and one with coanda, they could compare this and see the influence of the exhaust gases, even if the exhaust is not working as expected.
The worst scenario is that they fail to reach the operating window of the new tires during the test, which means they would gain no knowledge at all.
