[QUOTE="Deleted member 3831, post: 105351"] Smoothing can be used when making the initial measurements of the profile, but I don't use it because if there is roughness I would rather be aware of it. Normally it isn't a problem with lift, be it cam or valve, but the third derivative, jerk, can be a terrible mess and impossible to understand unless some smoothing is applied. Regarding the number of decimal places being used, 8 is the maximum available, but are not that often used. 6 are used frequently, and when differentiating the reason is apparent from a study of the attached graphics. Note the header which draws attention to one data set differentiated by subtraction, while the other shows the same data set processed by a curve fitting mathematics. [/QUOTE]
