To stay in your example: if something has a success rate of killing 1% of all cancer cells (which would not be very effective) , it fails at 99% of all cells.
A factor 20,000 imrovement would mean 0,99^20000 = 5.056988325166235*^-88 failure rate, which would effectively mean complete success in destroying cancer cells.
Alas I’m sure there’s a different math behind that increase in effectiveness.
