You need to qualify that statment.

There are conditions where supersaturation occurs, and the values are
significantly larger than 100%.


"Supersaturation" is used to mean relative humidity above 100%. Relative humidity, with
respect to water, in the atmosphere rarely gets above 103 % in clouds, the reason is that
droplets have something to form on. If you take a container with smooth enough sides you
could create 300% to 400% relative humidity before you would SEE the condensation.
