On the basis of the recent knowledge that the decay data measured by Total Absorption Gamma-ray Spectrometer (TAGS) is free from the so-called pandemonium, the prediction power of the gross theory of beta-decay was studied. By comparing the theoretical prediction with the INEL/TAGS data, we conclude that the gross theory predicts well the total energy release, or Eβ + Eγ. However, when Eβ and Eγ are dealt with separately, the prediction power of the theory has a limitation. This is one of the reasons why we need further TAGS measurements.
