Wind assisted results in combined events (0)
- Performances which are wind assisted or for which a wind reading is not available will be considered illegal. They shall be eligible for world rankings subject to a correction mechanism.
- Hand timing performances in 100m, 200m, 400m, 800m, 110m/100m Hurdles, 400m Hurdles and 4x100m Relay will be considered illegal.
- For the running events of 200m and over (including combined events), performances achieved on oversized tracks shall not be accepted.
- For the Combined Events at least one of these conditions must be met:
- The wind velocity in any individual event shall not exceed plus 4 metres per second.
- The average wind velocity (based on the algebraic sum of the wind velocities, as measured for each individual event, divided by the number of such events) shall not exceed plus 2 metres per second.
Higher average velocity was previously allowed as long as no individual event would exceed +4.0 m/s but the IAAF removed this rule in 2010.
On the website of Decathlon 2000 are used the following terms for wind assistance:
v event with wind >2.0 m/s and <=4.0 m/s and wind average for 3 events <=2.0 m/s
w one event with wind >4.0 m/s and wind average for 3 events <=2.0 m/s
v. all events with wind <=4.0 m/s and wind average for 3 events > 2.0 m/s (IAAF rule since 01/01/2010)
W one event with wind >4.0 m/s and wind average for 3 events > 2.0 m/s (IAAF rule until 31/12/2009)

v and w are valid for all records and lists
W and v. are not valid for WR or NR
for example:
v +3,0 / +2,3 / -0,5 / +1,60
w +0,1 / -1,0 / +5,8 / +1,63
v. +2,2 / +1,6 / +3,1 / +2,30
W +1,2 / +4,2 / +3,4 / +2,93
