Both "Model Coverage" and "Product Coverage by Model" require the Model ID and Place ID to be defined on the Line.  "Model Coverage" requires the Quantity to be set to > 1, whereas "Product Coverage by Model" will set the Quantity automatically based on the number of products that have the designated Model ID at the Place.  The Quantity field is more or less informational only; it does not affect price calculations.  So the only real difference is the setting of the Quantity field.

@Simon Wiltshire Do you have any idea on this one?
