That's a difficult question to answer when we really just focused in on the resources who were working on ArriveCAN. That's where the average comes from.
As I answered to a previous question, I would have expected that the dependency on those external resources would have reduced over time, but I also would have expected that the requirement to always ask for resources with 10 years of experience or more would have been better documented or justified. A mix is likely a better combination, of lesser experience and 10 years or more, and that would have resulted in better value for money for taxpayers.
