Another of my fact-finding projects.

The CoP does seem to have a negative effect on ladies' jumps, as it did in the past on men's quads. I looked up the protocols for the world championships and OG since CoP came into use and focused on ladies' 3Lz and men's quad (4T/4S). I counted all attempts – including falls, downgrades and edge calls, as the object was to check the changes in strategy in view of CoP, not necessarily the success of said strategies.

Here are the results for men's quads:

WC 2005: SP 10, LP 13, Total 23

OG 2006: SP 6, LP 14, Total 20

WC 2006: SP 7, LP 13, Total 20

WC 2007: SP 3, LP 11, Total 14

WC 2008: SP 5, LP 12, Total 17

WC 2009: SP 4, LP 8,Total 12

OG 2010: SP 4, LP 11, Total 15

WC 2010: SP 5, LP 13, Total 18

WC 2011: SP 8, LP 15, Total 23

WC 2012: SP 11, LP 22,Total 33

You can see that men's quad attempts declined steadily from 2006 onward, hitting its lowest point in something like 12 years in 2009 WC and 2010 OG. After the changes made post-Vancouver quads became popular again quite rapidly. We had a burst of quads at Euros and US Nationals and I bet we'll see even more of them in London.

The quad list was just an illustration – CoP caused a problem, was changed when the problem was recognized, problem fixed. Now on to the really interesting stuff – ladies' 3Lz.

3Lz attempts in ladies' programs:

WC 2005: SP 20, LP 27, Total 47

OG 2006: SP 22, LP 25, Total 47

WC 2006: SP 20, LP 23, Total 43

WC 2007: SP 21, LP 29,Total 50

WC 2008: SP 22, LP 27, Total 49

WC 2009: SP 22, LP 23, Total 45

OG 2010: SP 16, LP 22, Total 38

WC 2010: SP 17, LP 18, Total 35

WC 2011: SP 11, LP 22, Total 33

WC 2012: SP 8, LP 18,Total 26 (!)

3Lz's are down to half what they used to be just 5 years ago. Clearly there is a problem. Does the ISU recognize it? How do we fix it?
