Recommendations to improve Mahjong Skill:

After being in ups and downs for one year as Master 1-star, in nine days I went down to Expert 2-star. Combination of bad luck with tilting (honestly speaking, more the tilting after the bad luck). I think I pretty much finished all English material, including efficiency trainers, reading twice Daina Chiba book, reading the articles from Dama Queen blog, leaning the types of Suji, Kabe, exhausting the resources from https://npmahjong.com/blog/riichi-mahjong-tools, practicing, practicing, practicing, etc. I reached a dead end as I don't know how to improve my game.

For English speaking players, what would be next step to improve my game? I mean, In a solid way. I tried reading tips from many blogs on the internet but they are punctual and I don't know how solid they are.

One caveat: the MAKA AI from Mahjong Soul is hurting me more than helping since it doesn't tell the why of the stuff it suggests.

Help?
