But as has been mentioned by someone who uses these positions, the adapted position gives them an advantage compared to them using the normal position. Also, what I have quoted so far has been directly from the 2012 main shoot rules, more up to date the the 2011 clarification you mention.
Again, I understand the intention of the rules. However, it states simply that no advantage should be gained, and clearly it is.
I understand this is down to interpretation, but I am trying to get my head around specifically what is written, not what it is intended for, or what somebody wants it to mean.
