While it's true that Turkish local board is among the most merited ones (usually 2nd or 3rd most merited local board), you also have to take into consideration amount of posts written in Turkish local board which is also very high. When you calculate merit/post ratio, it turns out that Turkish board definitely has room for another merit source (not going into quality of posts there, speaking purely about the numbers).
Below you can see local boards merit/post ratio chart for April 2022 (May overview should be out in a couple of days) and you can notice that Turkish board has below average numbers when compared with other local boards (both April and last 12 months), and numbers for May will be even lower so I am not surprised that @xzone applied for a merit source position.

I know that there is always room to be a source of achievement in sections that have a high number of posts such as the local councils of Turkey, Russia and some other councils. I don't know why the OP would want to apply to be a merit source, although it's possible that the data you provided was one of the reasons. That's why I'm asking, and so far all the posts he's quoted have get merit from me form of support for it.
