I set the max depart to 100% and asked it to plan a round-trip route to friend's house (about 238 miles in a TM3 LR AWD). No matter what I do it has me leaving with 90% SOC and depending on how I manipulate the other settings it has me stop on the return trip for 0:00 to get and additional 2%. Obviously I can just ignore this stop if turns out not to be needed but I am trying to better understand how abetterrouteplanner.com works.
