"[LWC] limits have been calculated for a rotating cylinder..., and the results show that rotating cylinder measurements are of limited usefulness and may, in fact, prove entirely misleading as regards both water content and droplet size."
From: Fraser, et al., "Thermodynamic Limitations of Ice Accretion Instruments"
The term "freezing fraction" is defined (but probably not the one that you expected).
