Before revision:  Our validated model of RFstalling based cell division, can reproduce the variability in cell size distribution seen in these mutant strains, and provides a predictive tool to further examine stochastic effects in bacterial cell size regulation .
After revision:  Our validated model of RFstalling based cell division, can reproduce the variability in cell size distributions. In our model, multi-fork replication produces multiplicative 'noise' and provides a predictive tool to further examine stochastic effects in bacterial cell size regulation .
