The 
mark in AI is clearly valid from the beginning of the bar. In turn, 
in FE (→GE,EE2), apart from the literal reading, can be interpreted in several ways, e.g., as 
valid in this place or – which is more plausible – as valid from the beginning of the bar. In the main text we propose the latter, being the resultant of both source notations (Cf. also analogous bar 62).
In EE3 (→EE4) an arbitrary was added to adopted from FE (near the end of the bar), probably on the basis of comparison with bar 62.
