More explanation needed for website Run with example data feature

The issue is that this feature does *not* just insert example/test data into the WF run form, but also configures input parameters to the ones defined in the WF test.
Since all this comes from WF tests, everything can be highly tweaked for this purpose and the settings may be *very* suboptimal for real-world data, for which, hopefully, the WF defaults are the much better choice.
As pointed out by a user, when you're reading run with example data, this is not at all clear and you're tempted to just replace the "example" data with your own data and then get potentially very poor results.

What we need is a warning message that this mode may not use the WF defaults and should not be ued with your own data.
