Table is not readable well. The tack angle would be: 2*(90-Up.Bt)
In 4 knots of wind you tack 86 degrees while
in 20 knots you tack 100 degrees.
In theory. For this boat. And with no waves, and new sails and clean hull, ... each boat is different. But on my boat it is always close to 90 (while on a good performance racer it is much less).
