While that's a valid argument, it's not one that would be wise to use. One could simply counter and say that a mere $20m of improvements to Yellowhead would be enough to save 6 minutes on a cross-city commute which is probably a valid statement.
The fallacy in CTV's tests is that the majority of commuters are not doing Yellowhead from Henday to Henday, but rather an immeasurable number of intra-city trips that use only some portion of Henday. The average person who now uses NE Henday for their commute (as opposed to some combo of YHT, Capilano, Victoria, etc. that they previously used) is saving far more than 6 minutes on average, I'd guess something more like 10+ minutes. Because of this uncertainty, any fuel/GHG/commuter delay calculation is pretty hard but the savings in any of these metrics is far greater than a 6 minute average savings would net.
