Disinfectants claim to kill 99.9% of germs, but they can't guarantee 100% effectiveness due to the logarithmic decay pattern ...

While it might seem that science could eliminate all germs, the mathematical pattern known as logarithmic decay makes it scientifically impossible for products to promise 100% effectiveness.

The second mode, we set the decay mode to FAST_DECAY and we can see that the response is much more logarithmic/aggresive response. Slow_DECAY = linear response, looks like a 'V'. FAST_DECAY = ...
