Curious enough the ones that disagree are mainly active or retired Portuguese Air Force pilots, it seems they always did perform this proceedure with the VOR tuned all the way in. In my humble opinion it makes no sense, but better be safe than sorry
Thanks for the reply. I am going to speculate here - maybe if equipped with an old basic CDI (pre HSI) it was less confusing to carry out the turn using the VOR, thereby avoiding 'reverse sensing' during the first half of the turn, before flipping to the ILS once pointing 'the right way'.
