 ### Recommended material property sets
 In March 2023, the UMD Pyrolysis model (material properties defined in MaCFP\_PMMA\_2021\UMD.json) was identified as the most 'central' or 'average' model of those currently available. That is, this model yields predictions closest (sum of square errors) to mean gasification predictions. It is suggested that this parameter set by used by modelers for initial model setup (to provide a common set of parameters for MaCFP PMMA). It is NOT implied to be the most accurate property set.
