Looks good! As Dorico doesn’t have a Font Style or adjustment settings for slashes, I made one myself with a doricolib file and posted it in this thread.
Once installed, the doricolib file creates a functioning Font Style to adjust this:
Basically the doricolib file redefines the bass.slash and the bass.slashdiagonal glyphs to use the new Font Style that’s also contained in the doricolib file, so you can have easy control over this. I have the default percentages and yOffset values set to work the way I want with my fonts without further adjustment or editing, but obviously these can be edited to whatever you want as well.
