对于中盘发狂系的难度估计还是有一定问题,如果因此被困扰到的话我非常抱歉。
i still have some problems about determining the difficulty of the middle diffcult charts,I'm very sorry if you're troubled by this.
再度思考后,高难差分的难度标识应该有一些问题,实际应该为★18-20或sl12左右。 On second thought,the high diffcult chart's difficulty level may have some mistakes,actually it should be around ★18-20/sl12.
