• Partition protocol data and functional code.

• Find a simple way to test on real device data (this may be related to partition of the code).
• Define classes and values in a consistent way.

Every tree has a root corresponding to a class. The classes and context of each are supposed to be defined dynamically in artefact.

• Only median/AVG values when there exist more than one measurement.
• Handles refraktometri, keratometri and tonometri classes.

• Use sph_f in cycloplegisk refraction.
• Currently only support for sphere, cyl and axis in cycloplegic refraction.
• Handles refraktometri class.

• Handles refraktometri class.
