Since obvious a decision has been made to use the test patches for this event you, as the organization, should stick to the use of the latest test patch as it was already told at W10 and the following test patches that the balance between the cars was still under development.
That's why you should stick to remain in accordance with your earlier made choices regarding the use of test patches.
All racers were aware of the fact that test patches would be used for this event and as a consequence (small) moderations to the balance could be made. Like Orion said, it was the drivers choice to pick a car with that knowledge in mind, that's why now you cannot go back and say we stick to a certain level. That would undermine your own decision making.
And Josh don't start accusing of any unfairness towards Orion/ the organization. The alterations based on the balance have an impact on the organization and to start undermining the organization with some lame accusations is no good to the cause at all. Anyhow your apology is a better sign of appreciation.
I also can understand Orion/ the organization's point of view, but for me personally the above given explanation is considerable more weightily.
