I am trying to understand how far I can really go in my P85. What I have concluded is that .15 lowered this significantly. Prior to v6 my "Rated Miles" would drop about 1 mile for every 285wh used on the trip meter (Total energy used). This already annoyed me that it was at the 305 wh/m that the rated line shows. However, since getting my second firmware 6 version (.15) the problem seems to have gotten much worse with my Rated Miles dropping at 245wh/m. Making this this even worse is it seems to use quite a bit more power when the car is off- even for short periods. Are others experiencing this? I will note that the night of the upgrade my 90% charge set a high for me of 240 rated miles. Unfortunately it's back to 232 since then.
