Yes, the point is that it's not determined how many ones or zeros constitutes one time unit.
For one test case, time unit can be 1, and for another test case, one time unit can be 11, or 11111. So yes, a dot is one time unit, and a dash is three time units, but this means that if a time unit is three ones long, then one dot will be three ones, and one dash will be three time units, each of them three ones, what brought together makes it nine ones.
Oh god I am already scared of attempting this now lol
