I've been using the free TeamViewer.  Works very well.

This does not qualify as anything new.  I use a refurbished Dell Latitude rugged tablet which can go upstairs or down in a wireless NMEA data environment and then a refurbished Ipad mini for the cockpit when the tablet is hard wired to NMEA.  I use Team Viewer for mirroring Exp to the Ipad.  Has worked well for me for the last several years on a mix of wet and dry boats.  Lately, I find myself migrating to dryer boats.

Nick, Thanks for the response.

This is what I found. "ImportImport positions from a file. Several formats are supported, selected from the drop-list.Any position report file can also be imported by dragging it onto the race tracking window."

No joy for me.

Well, I still have not resolved the difference.  Spending time in race prep. But, I think it has something to do with the machines clock on my older laptop. Will get back on it after the race.

I'm routing an upcoming race.  Using the same polars, same weather download and parameters, same marks and same start time, I consistently get two different solutions.  The delta is only 4 minutes and change, but scanning through the solution I note there are different time stamps, up to a minute difference.  TWS can be a tenth different and TWD can be a degree different.

I presume this as being a machine processing issue.  Has anyone else come across this or am I missing something very basic?
