Energy of DMol3 Model different from DMol3 calculation

DMol3 Model: DMol3 molecular, task type: energy, Coarse, PBE, spin restricted. Energy: -922.73012851

DMol3 calcuation: task: energy, Coarse, PBE, spin restricted. Energy: -922.731612

The difference is small, but I am not sure it is reasonable. Attachment is a typical example.
