Everywhere USA Map software is training software for new sailors. We call changing direction when going into the wind tacking. A sailboat is not being powered during this period of time. Some boats and some sailors are better at tacking than others. It's like any other skill; it needs to be measured using a reference. The variables are many. This software measures and records tacking.
To measure small areas, the software uses "seconds" from the GPS library. Seconds cover an area of about one minute. The software picks any minute you happen to be in to display your tack.
I found several years ago that the "seconds" part of the GPS library had lots of random noise. After doing more research, the noise appears to be coming from my laptop computer or something in my office. Receiving those "seconds" outside appears to work well. The noise problem also applies to the other parts of the library, although not as bad.
