It is depends on what purpose the gambler use the lose record, i also record my winning and lose stats to know how effective my strategy was, but if the gamblers used it for recover the lost from previous gambling then it is wrong, because the gambler will fall deeper to the losing
I agree, because if they use their lose just because they want to recover they lose, it might get more losing than winning. Those people don't have enough self control if they do this kind of work.
