Although it may have the original intention to notate a 24-ET, it has  
been long known it isn't:

In Persian music, the symbols derives from Ali Naqi Vaziri, who  
intended a 22-ET, but it is known it isn't. But the symbols he  
invented are used today, then not referring to 22-ET.

So imposing 24-ET may lead to incorrect results also in notation when  
transposing, also in notation, apart from the fact it does not sound  
well in the MIDI files :-).
