I'd revise this a bit before going to management with it.

For starters, the scanning times are almost certainly too low. I suspect
that they are based on the theoretical transmission capacity of the
respective interfaces, but that is not what you'll have available. Some
capacity will be taken up by administrative overhead and (on USB at
least) by other devices sharing the bus. In addition, the scanning time
itself is not figured in - no desktop scanner acquires an image in two
seconds. If you want realistic times, you'll probably have to do test scans.

Then, your hourly rate is not the number to use in this case - it must be
based on what you cost the company. This figure includes stuff like
holiday, avarage paid sick days, benefits, taxes, etc. and may be
anywhere from 25% to 100% higher than you base salary.

Do your calculation on this basis to make it bullet-proof and then go
beat management with its own stick ;-)
