- Its analysis separates luck into overall, good, bad, and game-flow measures, alongside distinct attack and defense indices.
Field notes
The navigation groups analysis into player tendencies, head-to-head records, and separate attack and defense indices; the latter are described using tenpai value and points lost on dealing in. The homepage displays coverage totals of 1,968 matches, 23,988 hands, and 56 players, and says its personal match tracker aggregates results after LINE or Google login. The point calculator is explicitly described as requiring no registration.
