This forum contains threads to discuss teams themselves. Anything not technical about the cars, including restructuring, performances etc belongs here.
When Red Bull were penalised for the budget cap breach, someone showed a list of what that meant in real time compared to others, ie, how many hours per week for laymen to understand, and they still had nearly 40 hours access they could use every week for 10 months.
So the team with the least wind tunnel time could still operate in it for 8 hours a day, Monday to Friday if they wanted.
Translate that to Mercedes, who have more hours available, and the issue with upgrades in season becomes clearer. Mercedes are definitely not giving up any of their own time just so Aston Martin can use the tunnel.
I wouldn't be shocked if AM haven't used near their full allocation.
