We left the unit on for 4 days... So there's a lot of data. I presume the landing point was at 7459 sec. 

Here's the data string

outside temp (C), relative humidity (out of 100%), outside temp (F), inside temp (C), dew point (C) (the air is so dry below -10 that it doesn't matter), pressure (divide by 100 for inches of MG, but not sure how accurate ..), altitude (wrong), time (seconds since the unit has been on),
