Yeah I remember watching this same clip and without saying it exactly, Ben pretty much admitted that they had close to zero confidence in their last sim/modelling and were going to be using T6 extensively for verifying the output from their new modelling rather than specific parts testingNo need to pin it specifically on the F1 team, BA has the same doubts on the AC36 VPP, he said that clearly in a recent interview. I’ve forgotten where.
