APPENDIX C--FINA DEGREE OF DIFFICULTY FORMULA AND COMPONENTS
Degrees of difficulty for dives are calculated using the component values of
the formula shown on the following two pages. The formula is:
A + B + C + D + E = Degree of Difficulty
Please
note that the "D" component appears twice. Choose the version of
component "D" that applies to dive being performed.
As
a guide, a list of previously calculated degrees of difficulty follows the
formula. In this table, empty spaces indicate the degree of difficulty has not
been calculated. A "--" indicates the dive is not possible.
Every
effort has been made to ensure the accuracy of the entries in the table, but if
any entry varies from that arrived at through use of the formula, the
formula-derived degree of difficulty is to be applied to the dive in question,
according to the USD FINA Technical Representative.
The
source for this information is the FINA DD Formula and Table of DD in the FINA
Handbook 2005-2009 (as amended by FINA March 14, 2006).
Degree of Difficulty (DD) is calculated by adding: A + B + C + D + E
A.
