• This preliminary application, if properly optimised, can be considered as an alternative solution to the classical methods such as the Staircase or Dixon methodologies. The methodology resulted in advantages in terms of testing time and number of gears necessary for the analysis. As a matter of fact, the F pn ∾ was estimated 10 times faster with respect to the value obtained with the Staircase Method and with one gear. References Attermo, R., Östberg, G., 1971.
