Very level

laser level
Good level on the crown.

The laser shows a level surface on the crown. Some small adjustments with a diamond wheel and angle grinder were needed to remove some slight banking in a few places. These irregularities were caused by the self-levelling screed that cured far too quickly on a warm summer day in July. If I were to make the crown again, I would have made the top edge of the crown's form level, and used this as the reference surface for the trowel. Having done that would have made the screed unnecessary.
