If the problem is not a lack of quality staff then it is surely poor facilities and resources. Just like KFC will never be able to produce haute cusine....
Maybe the design team is brilliant but the wind tunnels give the wrong data, 50% scale models are not represenative enough, calibrations are wrong etc.
Let us not forget the team do not have a winning pedigree and that is for a reason, their facilites are not championship winning.
I dont see how a move from 50% scale to 60% will do much when Ferrari et al are already running close to 100%.
The bold part I don't believe. As far as I know, mercedes actually have two 100% scale wind tunnels. Their use, as with all other teams, are heavily restricted under teh RRA. I believe teams can trade straight line tests for 100% scale tests.
But as far as I know, 60% is the largest one can go without incurring severe restrictions. Therefore, I doubt ferrari or anyone else are consistently running 100% as you are suggesting.
Edit: Timstr11 beat me to it..
