We present a new approach in considering and including both the perturbative and the nonperturbative contributions to the multiplicity ratio $r$ of gluon and quark jets. The new method is motivated by recent developments in timelike small-x resummation obtained in the $\bar{\rm MS}$ factorization scheme. A global analysis to fit the available data is also presented.
