Default Resource for Bacterial RNA-seq depth recommendations

This paper "How deep is deep enough for RNA-Seq profiling of bacterial transcriptomes?" (https://bmcgenomics.biomedcentral.co...71-2164-13-734) does a nice job of going through the key library prep and sequencing depth parameters for a bacterial RNA-seq experiment, and concludes that "5-10 million reads per sample [...] are sufficient for most applications of bacterial RNA-Seq".

From my experience, the critical experimental design question for a bacterial RNA-seq experiment is how well will the rRNAs be depleted (i.e.: how many reads will not be covering target genes) and how many replicates can I perform (i.e.: what will be my statistical power). Depth is helpful to overcome poor rRNA depletion but adding more replicates is the better use of increased sequencing cost, in my opinion.
