This is what I logged after everthing was powered on for over 24 hours and adjusted. It is a 2 hour period during which no adjustments were made. http://www.uploadarchief.net/files/download/lpro_24h.png And this is with the LPRO is cold started. About 5 minutes after lock. The GPS was already running for about an hour I have to guess. The LPRO was not adjusted anymore. http://www.uploadarchief.net/files/download/lpro_start7h.png It is less flat at the last two hours than what I was hoping for.
