Just about when I lost faith the subject of factoring came up. Now the gorilla is in the room. Spin it anyway you want, if a company can get a factor to buy in then its real. And if it can survive with money at this price then, as the song goes, it can make it anywhere.
Your math is fuzzy. The percentage is still 4.67% regardless of the length of time. 4.67% per month, per year, per 100 years. You're not supposed to multiply the percentage by the number of periods...that's totally misleading.
