Yes parleys summit was my second summit and it was also the lowest mark on the GOM. Sorry I do not recall the exact reading.
I should also mention that I was not doing an economy run up the hill. I was doing 65 to 70 on the uphill side and it was great fun to pass so many gas guzzlers on a steep hill.
On the downhill side I put it into ECO mode to max out regen and it did gain bars, but again I did not record how many. Next sunny day I will do it again and keep better records. The main thing was that the car did make it on a single charge and it was a lot of fun doing it.
