I would remove the random values, because they'll be confusing for
people when they re-run a scan. I would leave:

- all variants of form element values
- top/bottom values
- top/middle/bottom values (maybe this could be the default?)

Yes, once you have one working... it's 10 more minutes of work+testing
to make the other one work.
