MuseScore Note Spacing Problems and MuseScore has no fixed spacing ratio.
In MuseScore, the spaces of some kinds of notes are not same normally. The upper system of this picture shows 1/8 notes have several length of spaces, and this is not good. In the lower system of the picture, 1/8 notes have only one length of spaces, 1/4 notes have too. Each kind of notes should have each length of space. Same kind of notes should have same length of spaces. I think this is better.
I found that MuseScore Always changes Spacing ratio. When I makes score by MuseScore, I Always measure each distance between notes and adjust space equal. It seems MuseScore has no fixed spacing ratio. This fact makes it hard to adjust spaces equal. When I adjust the spaces of one kind of notes, other kind of notes are not equal. I think Notation Software should have fixed spacing ratio in every system.
By the way, when I adjust spacing I use invisible rests and also adjust Segment in Inspector.
MuseScore3 doesn't allow me to use the way inserting invisible rests. https://musescore.org/en/comment/875146#comment-875146
