  • If you have applied smoothing to a channel, and you create a maths channel that includes that channel, the maths channel will use the raw data only. You can, however, apply smoothing to the maths channel.

For example, if you are running a Decel Test (60 – 20 mph), any selected runs displayed in the graph will start at 60 mph and end at 20 mph, even if the data samples closest to the test criteria are 60.5 mph and 19.6 mph.
