Report a calculation mismatch
Record the following details so a calculation can be reproduced:
- latitude and longitude or a non-sensitive public location;
- date, local time and displayed time zone;
- window orientation or obstacle bearing;
- verified obstacle height and distance, including how they were measured;
- the observed transition time from sun to shade; and
- a screenshot with private addresses redacted if necessary.
