Hi Roland, Looking again ...

... I think it is a misinterpretation of the documentation.The range is defined using the start and size (extent) of the range, so the range is [start, start+size]. The range is then output using the start and end values of the range: [start, end]. So, a start of -90 and size of 73 result in [-90, -17].
This one is pretty easy to get tripped up on as start/end seems more natural, certainly for me anyway. Let me know if we could clarify our documentation somewhere.
