To me tried 'n true means that the person posting has made the recipe at least once, and probably more than that.
Would never post a recipe I had not tried without stating such, and always try to give the source whenever possible.
Of course, sometimes people just want some ideas and we will try to come up with them, untried.
But I think if folks post a distinct recipe they should state whether or not they have tried it.
Have found the great people here very good that way.
Thanks to y'all and have a fantastic day.
