BLM/liposome methods have much lower MW and logP (MW = 159.4 Da, logP = 0.3). This is probably because these methods are not commonly used for extensive drug candidate molecule assays; rather, there are only a few measurements of typical small molecules (e.g., benzoic acid). These data are then often used as training/validation of different computational methods since they are not influenced by the -8 and -4 thresholds that are hard (or even impossible) to overcome for other experimental methods.
