There was an addition of only
12 samples with in general very little changes. The only change worst
mentioning is about lignin. We had data from donor labs that were added to the
calibration. This addition seems to have decreased performances. However, this
is an old lignin equation and its accuracy may be lower than the SECV may show.

This was the calibration that
has received the largest number of samples for updates (#26). From the donor
labs we had information on FAT and Lignin that were included.
Compared to the previous year
changes in performances were small. Relatively speaking, the largest changes
were on Fat and Lignin showing increases in number of samples ( over 10%) with an increase in error (SECV) for lignin, but
a decrease for FAT. We think these two parameters would greatly benefit from
chemistry coming from donor labs.
