The number of surface points is inconsistent with the number of geo_model.solutions.block_at_surface_points

[Linya-Peng]

What is your question? Hi~ I am using get_started.ipynb for a simple test. In this example, we have 8 surface points,

but why does block_at_surface_points (3D array with all interpolated values for a given series and at the interface) have 10 values?

Did I misunderstand something? Thank you in advance
