All range estimates are guesses. Unless they can use weather and wind predictions, predict traffic flows hours ahead, and read your mind as to how you are going to drive today.
It is a GOM.
Which is why I like the fact that they give you middle, low and high values, and you can take your pick. The Volt and Spark both used a much better algorithm than the LEAF, as it apparently used a rolling average over a much longer interval than was the case with the LEAF, and I imagine the Bolt does likewise. So, sure, they're all estimates of future behavior, but some are a lot more accurate than others.
