This calculator will help you to determine the D-max point based on your data-set.
Detailed explanation is in the article.
The default example has 10 data-points.
You can add more data-points (“+Add row” button), but you cannot have less than 10.
In my opinion, if you have less than 10 pairs of data, you don’t need math. Just choose the D-max point visually.
Enter your data and click “Calculate”.
Do not leave empty rows!
All results will be displayed in the bottom-right box.
