We don't have them for the other input types, and I believe that it's not the driver's job to compute and export these values. If anyone cares about the history of sensed values, that's something for a user-space application to implement. This will also be much more flexible in user-space, as it becomes possible to decide the exact time range to consider, to remember at which time the peak occurred, etc. -- Jean Delvare
