That is not necessarily a saving. If you have a let's say a team of five people each costing $1000 a day, those idle 6 days (not counting the weekend) would add up to $30k of wasted money. Then if you are working on something the competition is also working on, these lost days would add up and potentially cost losing the edge - could be quite expensive or even cost the business.

Agreed. When I mentioned lower costs, this was exclusive to model training, but there are so many other factors that influence the cost to a business.
