Still, using negative values is more than difficult for statistical assay, and for comparing results. The procedure for the Presidents Challenge version crave that the box is made with 9 inches (23 cm) at the level of the anxiety, then reaching two inches past the toes is recorded as 11 inches. The Eurofit manual suggests having 15cm at the level of the feet, and also 10 inches has been used (NHL combine testing).

The modified sit and attain test controls for this, as the zero mark is adjusted for each private, based on their sitting reach level.
