I see what you're saying, but 60% of time spent doing something else than research, is not a research position. That is no way to be productive as a researcher. The upshot of this is what I point out in my other comments, that you end up offloading the research work to PhDs and post-docs while you take the back seat and of course keep the funds coming so that they can do their job.

... although my PI didn't :)
