Technical question on tactical computers and racing tasks

Most default to perpendicular to the first leg which would go to the turnpoint. But you can program in a different angle if something different is called for.

At the 13.5m WGC the finish line was aligned with the edge of the airfield, not the final leg, for example.

Thanks. Yes I am aware you can set the angle, but wondering what happens in most of these programs if you don't. And secondarily, what is the typical practice of racing rules worldwide.

Most are perpendicular to the path line from the last turnpoint to the finish or start to fist turnpoint and 1 km wide (for those not handicapped by an outdated measurement system).
