Within the section for a given test condition, the repeated readings for each part are entered in columns, as shown below.
Therefore each row within the test condition area represents one complete set of readings for one test round for that tester.

Because macros were avoided, the messy details of the calculations appear in the next section. If they make one nervous,
just hide them, and go directly to the Scorecard. One may, however, find these calculations helpful. Here is how this sec-
tion is organized:
The first table in the calculations section shows the average reading for each part for each tester. Be sure and note the color-
coding scheme to keep track of the headings in the table. Headings pertaining to test conditions appear in purple. Headings
for samples appear in yellow.
