I do find myself looking out the window as it goes back and forwards making perfect stripes. I haven't found any variation in the RTK GPS accuracy based on where on the property it is - it's always sitting at 10mm. The exception is when it's on its charging base right under the RTK antenna where it bumps to 20mm.

As for getting along the edges, the Lymow has two settings, Precise and Offset. For the first few runs I had been keeping it on Offset but today I've changed it over to Precise for most of the zones. In Precise mode, it's getting right up against the edge, taking the exact line that it was mapped on and running against the fence line - probably a little closer than what the guy with his ride-on was getting. I will probably keep it on Offset mode for the zone with the growing hedge and use a trimmer for the offset line, just to avoid mowing down any young plants.
