It may be better, but I generally look at my current Wh/km usage for an estimate of my remaining range.

Average over 130000km (3y) is 191Wh/km

Winter can be as bad as 330Wh/km (-30C 110km/h)

Summer can be good, but I've never seen a 100km trip better than 145Wh/km.

Generally the lower the remaining range, the better the EPA range (estimate) is.
