How to write functionnal complex metric modulation ?
Hello, i would like to use this metric modulation in a part. This is to be used as a playback for practicing so it needs to be read by musescore. All the solutions i found are about using an image to inform the player but that's not what i'm looking for.

Create from an existing one, using the special characters table and manually tweak it BPS setting
I understand the image to mean that five eighth-notes (a quarter note + a dotted quarter note) in the old tempo should take as much time in the old tempo as four eighth-notes (one half note) in the new tempo.
new tempo = (5 * old tempo) / 4
See the wikipedia article for metric modulation.
You will have to type in the new numbers yourself, as fara as I understand.
You write "in a part" with might mean that you only want to have a new time signature for one part, but the other parts should still be in 5/8. This makes it more tricky. It you just want it for playback I think you should go for tuplets instead.
To elaborate on what Andreas wrote, you'll have to set metronome markings before and after the modulation--in this particular case, the subsequent MM should be 1.25 times (or 5/4) the previous one. So, if you have eighth-note=84 before the modulation, you should make eighth-note=105 after. You might end up with some pretty weird tempo marks, like quarter-note=67.2, but so be it. Uncle Elliott's scores are full of tempos like that.
If you don't want the metronome markings visibly written out, you can always hide them with "v".
