| Feb 14, 2022 at 21:28 | comment | added | Albert | I made a calculated field to show $id and this is correct - 1st record has $id 1, second $id 2 etc | |
| Feb 14, 2022 at 21:27 | comment | added | Albert | The transformation resulted in values now in the range of 10-9500 (ie now too big!) and still bearing no correspondence with actual spacing (ie large spacing does not necessarily have large values). | |
