Hi Alexandre, so the free time ratio is 720 hours (the total amount of hours in a month)- the time you spent on bed- your total time you spent for business. The spreadsheet that you can copy explain itself better. Also, not just the $/free time isn't yet the ideal. It's important metric but as I wrote, is easy to trick. That is why the power/freedom rate is so important, it is the north star and all the rest just support this one. Based on how your values look on this spreadsheet, you can see what is wrong and make conclusions. I was thinking about put the conclusions, but I think it is such an important and particular thing that people should figure it out by themselves. But for myself for example, if most of the parameters look red, I should not improve what I'm doing, but change the matter of what I do.
