  We perform a thorough analysis of the spectral statistics of experimental
molecular resonances, of bosonic erbium $^{166}$Er and $^{168}$Er isotopes,
produced as a function of magnetic field($B$) by Frisch et al. [Nature 507,
(2014) 475], utilizing some recently derived surmises which interpolate between
Poisson and GOE and without unfolding. Supplementing this with an analysis
using unfolded spectrum, it is shown that the resonances are close to
semi-Poisson distribution. There is an earlier claim of missing resonances by
Molina et al. [Phys. Rev. E 92, (2015) 042906]. These two interpretations can
be tested by more precise measurements in future experiments.
