I think he missed it in COC in 2011 (during the FS, which made him really angry because it is his money jump) and once during his 2010-2011 FS (he slipped when he landed it and fell, but I don't remember I which competition it was). Other than that I don't remember him missing it: his fall during this year's COC is a proof of how difficult this programme must have been for him...
He also missed 3A two times during 2013/2014 season - Finlandia Trophy - in SP just 1A, Skate Canada - in LP 1A+1T.
