The following two threads may be related to this thread:
In the case I have discovered,
the notes are adjacent to each other, but the placement of accents are not coherent.
Do we have now a possibility to align the position of accents either to the inside/outside of the slur, not using Engrave mode?
To my eye, it seems not to be optimised. I currently work the score for a performance, thus I do not work for the layouts, but I think it would be better to align accents in the same positions in the example attached.
However, it is theoretically correct according to Gould on page 122: Articulation marks in the middle of a slur go inside the slur. Accents at the beginning and end of a slur usually go outside the slur, so that the slur can remain closer to the noteheads:
