I think spending 10% of your time on sync meetings is totally expected (at least in scrum) and doesn’t feel too outrageous to me.

For myself I have learned the total amount is rarely the problem but when meetings are. I am most productive in the morning hours so I asked everyone to schedule sync meetings in the afternoon and I have told my team I will not attend dailies unless it’s requested or I have some action that needs to be taken. Works out pretty good so far.
