I’ve got a whole bug-reported, feedback-logged thread on this. I moved a lot of them in Northern California airports while the World Hub was open, just waiting for that to come back so I can resume working on it. But yes, it’ll take a lot more effort.
In terms of angle, the individual LHAs seem to be correct - keep in mind that 0.2° at a distance of 1500’ (roughly 1/4 mile) is only about 5’ vertical difference. I think the bigger difference is the relative lack of depth perception and pitch axis (over)controllability that causes abnormally high sink rates.
But at the end of the day at a lot of it simply comes down to incorrect longitudinal placement.
