So as per THE RACE podcast, AMR struggles if circuit has wide range of corners that is high speed and low speed ones needing car car ride to be set up not very low (for DF) and also not very high. They can't get that good compromise optimum setup to work in high speed and low speed.
For me this tells me canada upgrade (which dan fallows said is get car working in all types of circuits) is yet to work as expected.
Hopefully If they can improve on that set up this week and also the new strong front tyres this week as suggested in some articles work in improving the front grip might help them in doing better relative to Austria
