this is something i found by googling erection hardness scale. not sure if it's what you are referring to, but it does at least change the direction this thread was headed..
EHS rates the hardness of erection on a scale of one to four, with four being the maximal score. The language used is simple and direct, so that men with ED can use the scale to assess the severity of their condition and to monitor the impact of treatment. A score of 1 indicates that the penis is larger than normal, but not hard; 2 means the penis is hard, but not hard enough for penetration, 3 means the penis is hard enough for penetration but not completely hard, and 4 indicates that the penis is completely hard and fully rigid.
