Blood Saturation, THC Calc, etc.

I know it's been said that the old THC calculator does not account for potency, daily smoking frequency, etc...but...based on this statement:

"THC is stored in fat tissue. It works like this; Each time you get stoned, you saturate your blood with THC. Blood saturation reaches 100 percent fairly quickly and can't be exceeded. (keep smoking and you are wasting good pot). Assume that all 100 percent is absorbed by body fat. Body fat dissipates THC at the rate of 10 percent of total fat saturation per day. This means the day after you still have 90 percent blood saturation. The day after that you have 81 percent blood saturation left. etc... Current urine tests can detect 60 percent blood saturation. So if someone has never smoked pot before smokes one time, it takes three to seven days to dry out. However if you smoke every day your fat saturation level climbs to 1000 percent! This is maximum because you lose 10 percent of 1000 percent every day (100 percent blood saturation), and can only attain 100 percent blood saturation every day."

If that statement is true, wouldn't potency and frequency of smoking not matter? It's saturation...you're blood can only be so saturated with THC....ie 100% So...if you are at 1000%, it takes approx 30 days to be clean (as per the calculator). This seems to fit in with a lot of reading I've done. The real chronic smokers need a minimum of 30 days to be completely clean. Where is the misnomer in the THC calculator? Is the 60% saturation number wrong? Has that been lowered with current tests?
