The most difficult in this approach is the empirical coefficients A and b in the formula (2.6) is unstable which depend on rain distribution function according to size, ie at ND. This factor did not change significantly over time and space even in a rainstorm. Thus formula (2.7) given by Palmer Marshallva sometimes lead to large errors in estimating rainfall.
