Arrival SoC Way Off On Some Routes

ABRP is pretty much dead on when calculating the arrival SoC traveling southbound between Tacoma, WA and Portland, OR in the US. On the reverse, northbound, trip it is off by a significant amount (say 10% SoC at the destination, even when “overcharging” at the charging stop) – enough to require second charging stop or a “white knuckle” arrival at the destination.

I’ve noticed this on a couple of recent trips (but don’t recall it from earlier trips, so it may be a change). I don’t think it is related to significant weather differences, except perhaps the wind.
