Doublings can be avoided by eliminating the registration of leaving an antenna. Excel compares each position of the animal in the column with the following position recorded. Depending on whether the registering antenna has changed or not between two measurement points, Excel notes a one or a zero in the next column. (A) By summing up all entries, the user receives the number of field changes over a chosen time period. (B) Using this method, Excel frequently counts more field changes than the animal actually performed.
