In the Modified Leading Logarithmic Approximation (MLLA) the multiplicity difference \\delta_{Q\\ell} between heavy and light quark jets is derived in terms of a few other experimentally measured quantities. The earlier prediction for b-quarks needs revision in the light of new experimental results and the improvement in the understanding of the experimental data. We now find \\delta_{b\\ell}=4.4\\pm0.4.
