You can get a pretty good idea of quality of project management based on how well or poorly they estimated project baseline costs at outset. These are linked - incompetence in estimating costs / complexity = incompetence in execution = insane cost overruns. And you would get far more science with 5 $2B projects then one project like this. And if this thing has a launch of deployment problem all eggs in one basket. If there are cost overruns and delays, also all eggs in a basket and no other options.
