Xuanxuan Qijing/Gokyo Shumyo is far more reasonnable and is probably good for low dan

The day you can solve the Igo Hatsuyoron problems in less than two minutes, you have memorised all of the solutions. I kind of doubt even pros can solve some of the more difficult ones in there without knowing the answers in two minutes.

And on top of that, with some problems it takes more than 2 minutes to lay down (or even visualise) the solution, because the sequence is so long
