I'd be more comfortable with a real random (at least pseudorandom) number. Humans are terrible at generating random numbers and information could be given away on account of this. For example, people tend to favor 5s and 6s when generating "random" large numbers.

Ok, I picked a fake random number with my terrible human random number generator. I added my salary and got 65419563.

It's easier to guess someones salary than it is to guess the random number they generated (in order to figure out their salary).
