Exactly. The protest clearly isn’t with RB - they’ve done nothing wrong and no suggestion they have. But if a SC is deployed and you have a set of rules that determines if you pit or not, then those rules change at the drop of a hat - you have a significant reason for protest.
You're right, of course.
However, Bono (I think it was) clearly told Lewis on team radio that they didn't pit because they'd have lost track position.
