Porsche Planner Route Monitor - Battery Charge When Reaching Target

[GasStation]

The Route Monitor in my Porsche planner always appears to over estimate the planned route consumption by 4% to 5%.

Anyone else notice this or is yours bang on the money?

Case in point: Battery SOC = 45%
Porsche charger estimate consumption of trip from point A to point B = 20%, therefore remaining SOC predicted to be 25% reamining at destination (% in top right corner of Porsche Charger screen)
Actual consumption = 15% and I end up with 30% remaining at destination.

That often happens, but for 5% off (over estimating the consumption), I am okay with that. I am currently seeing an under estimation by about 3 %. it would be very difficult to be exact especially at the start of the trip, as weather temp, wind, elevation, start/stop feq, and many other factors (including the weight of your car now vs when the data to was created for your current estimate.

Within 5% I would consider good, but only in the case of over estimating consumption. I worry more about the underestimating and getting stranded without power.
