you told me Sunday that you've given up on the interweb
I think your photos are great and informative in defining the AGM proposal. However,this thread was about finding out if that definition can be improved. Why? Because a number of BFTA shooters felt that they needed to have some form of ankle support whilst kneeling.
In 2009 the very same problem was discussed by the BFTA; so hardly fictitious
! FFTA proposed a very similar definition as to the one that was passed in 2013. In 2009 it was rejected because it was felt that some shooters needed to be able to support their ankles!
In Olympic 3 position the competitors are allowed to support their ankles then why not FT?
