Is this the first quintuple turn ever attempted in competition? Check it out after her 2nd tumbling pass (starts at 39 sec):
Marta Pihan-Kulescza Floor - 2015 Europeans EF
I'm not sure if the judges gave her credit for that (she really started falling out of that after the 3rd spin), but I do not know of another gymnast who has attempted this in competition. We've seen an increase in quad turns in the past several years - some of which are completed and some of which aren't - but a quintuple is insane. If you know of another gymnast who has competed a quintuple turn on floor, post a comment!
One final question....did your eyes catch it?
