Great news, I'm glad it did!Yincognito thanks.
Following your guidelines, I decided to redo the code with your suggestions and it worked.

The problem occurs because the %a format returns the name of the day of the week in text (for example, "Mon", "Tue") and not a numeric value like %w. The measure of progress in Roundline relies on numerical calculations. To solve this, you need to map the days of the week in text to numeric values in another measure.
Regarding the %a suggestion in [M-Day], it was exactly what you had with %A and the Substitute there, just easier to apply for the day of the week as an abbreviated string. It had nothing to do with [M-DayIndex], which retrieved the day of the week as a number via the %w format. Those two are separate measures, and obviously you'd have to use either the string or the numeric one as needed in your other measures and meters, like you said.
