The maths don’t add up.

16% of 40 hours is 6.4 hours, not 1.25… 6.4 hours per week amounts to 1.28 hours per day, and 20% of that (the failure rate) is just over 15.6 minutes per day being unproductive… or about 64 hours per year, based upon 50 working weeks per year.

At US$30/hr (60,000 / 2000), this amounts to a cost of US$1920 per person per year lost to unproductive searches, significantly more than the US$375 you suggest… you therefore underestimate costs by a factor of approximately 5.

Unless I’m missing something…
