Any uncompensated time invested by owners can be measured in weighted hours.
(like founders working around the clock pre-money or executive staff earning a few weighted hours a week in addition to a salary)
Risky early stage investments counted as time invested in the prior year to earn that money by working a job.
(like founders investing hard-earned savings from previous jobs to give the company working capital)
Any other financial investment at lower personal risk counted as present and future time purchased for the company.
(like a privately wealthy founder drawing from family money or more traditional later stage investments)
1. Time invested is given weight by the year that time was invested
1 hour invested in the first year of the company = 2 hours invested the next year
2. Earned income is given weight by the previous year when the income was earned
1 hour of earned income invested in the first year = 2 hours of time invested that same year
3. Cash investments are given weight by the year that cash will buy time
1 hour of time purchased in the first year of the company = 1 hour invested in the same year
