Zspeedaccuracy question

Hello everyone,

I'm doing some work on validating some data to do with the zpseed functionality around corelocations, i've read up on the speedaccuracy field but the wording doesn't make sense to me. It says if its a positive number it is plus or minus the value in the zspeed column so would this be for example zspeed of 35 mps with an accuracy of 3 mps would it be 32 mps 38 mps or is it a range? so would it be anywhere between 32-38 mps. Or is it just plus or minus the 3mps and if this is the case how would it be worked out if its plus or minus when all the numbers will be a positive numbers as any negative numbers are deemed inaccurate ?

It's an error range, as in +/- the data point.

If the accuracy is 3mps and the speed is 35mps, the actual speed could be anywhere in the range of 32 to 38 mps.

Also, don't forget that the speed is the instantaneous speed at the time of the creation of the location event and could be different by the time you have processed the data or the next location data has been delivered.
