A 3 meter drop reaches a peak velocity of 7.66m/sec (~26ft/sec) which is less than the maximum terminal velocity. of either of the above examples.
The definition of terminal velocity in the context of this thread is given in the first paragraph of this web page:

https://en.wikipedia.org/wiki/Terminal_velocity

Please read it.

You are using a different definition.
