SPI = 1 but WP is to late

At the moment the SPI is calculated everytime, but never saved. That leads to this Issue, because the database has no memory of the spi. Meaning: if the wp is finished with an spi of 0.5 each day after it is finished the spi will increase until it reaches 1.

When the wp is closed the SPI has to be saved in the database. No values of the wp should be calculated when it is finished and the saved spi has to be returned instead of a recalculation.
