On the relationship between the value of the latent period and the height of the wave of tendon reflexes in the graphical research method

In the literature on the issue of tendon reflexes, as far as I know, with the exception of the works of Eulenburg and Féré, there are no indications and special works concerning the observation of the ratio between the size of the latent period, the height and length of the muscle. Apparently, these parts of the graphical depiction of reflexes should be in certain relations one to another, expressed approximately by the formula expressed by the mentioned scientists that the magnitude of the latent period and the magnitude of the reflex are inversely proportional.
