@Skully62 That's a good question.
The router does not always get the exact optimum VMG angles right.
If the optimum is at 153 it may sail at 150 and there will be a false flat spot in the isochrones between 150 and 155. Always use the track tool and the polars to check the optimum angles.
One previous version included points of sail outside of the useful range and it would sometimes sail there, which is usually worse than staying in the range, even if a bit below the max.
Also, the router accounts for sail changes but the track tool does not.
А sail change makes the dots overtake the isochrones, and it may be noticeable, especially without PRO winches.
