Nope, I was providing a visual representation of the fact that just because we don't see what IPIX is doing every day does not indicate a lack of forward movement.
I have decades experience managing IT projects and spent more than a fair share of that time soothing nervous Sr Mgmt. Of particular annoyance were those who'd just read an airline magazine article on IT projects or had a pre-pubescent child who was a "whiz at computers" who advised that it was taking too long.
The statement "IPIX knows not what critical path scheduling is." sounds like there's been some recent air travel.
Perhaps you should contact Leo and suggest he assess "liquidated damages" against external dependencies such as the FDA, CROs, and cohorts.
