> So, for example, if you get a new versions of excel, which improves your productivity $100/year, but excel costs $100 this year to upgrade, you haven't gained anything in year 1.

Yes, but this is a tautology (it will always be true that making a capital expenditure of $x/employee/year to augment surplus value $x/employee/year will break even). Productivity itself is scalar (units produced/time), so to arrive at a dollar amount of $100 additional revenue generated per employee would suggest an incredibly small increase in units produced over 1 year.
