I think this topic has been discussed in the old thread. Back in the days when people are still using Invitrogen Ribominus kit, 30-40% rRNA in a RNA-Seq data is quite good. The new kits should perform better. In my own experience, percentage of rRNA in the data depends very much on the mapping parameters you use. I can map 30% if I allow 2 mismatch in 50bp reads but up to 50% if I use a min of 30bp extract matching. That's a huge difference.
