Optimized routes and resulting wind angles

When optimizing routes the output keep returning courses where TWA is below 40 degrees and outside the polardiagram (and possible sailing angles). One routing suggest sailing 21 nm in TWA 30 to 2 degrees. What am I missing? If this in the beginning of the reace, the rest of the routing is not so useful as there will be a mismatch between where the boat is and where the routing expects.

Re: Optimized routes and resulting wind angles

If you have a () around your small TWA  numbers, the Fine Manual will tell you that this implies tacking or gybing is needed. (I missed it too)
