I upgraded to Stargazer a couple years ago on a 2004 SN 196. It seems like the system works very well but I am curious how much the speed should fluctuate during a pass. Times are always right on the money but as I watch the speedo I noticed that the speed can increase up to 35.5 mph and go as low as 33.2 during a pass. I realize the the system must make up time during a pass but is this normal and is there a way to soften this increase and decrease? Just curious I guess.
