TC, as before, the duplicates were with the downloaded data, not your NASI A/D sheet. In most cases for the more recent dates, the second date represents a corrected value, so that was the one I went with. However, once I linked the values on the NASI sheet to the new data, the returns changed considerably, so there must have been some differences. As far as which set of data is "truth", i.e. unicorn or DP, I really could not say. If someone has access to the DP data directly, I will download that and do a compare.
