The best way to get an accurate measure of your remaining range is to set time compression to about 512x and ask the navigator to report the remaining range about every 2 or 3 seconds until you have 4 or 5 reports.

you can do the math by pencil and paper or just guess at an average of the 4 or 5 numbers. this average is your best estimate.

usually his first estimate is in error by a large margin, so it is best to ask for 4 or 5.

Could you please expand on this a bit. Why does 512x TC improve the estimates? I have been getting estimates at 1x TC thinking they were close to accurate.

Also, my navigator advises me that we get much better range at 3kts than we do at 7kts. Does range jump higher at 8-9kts from what it is at 7kts or is do I need to replace my navigator when I get back to port?
