I'll engineer it for the type of running I want first, thank you very much.
Running a Yugo at Indy does not make sense to me, I'll engineer what I want to run since I have a good idea of the conditions.
Dirk has a goal, and he knows what he wants to accomplish, so some testing first makes a lot of sense.
Just like the testing Ted Doskaris did indoors with Aristo couplers BEFORE he went outside with grades...
I gauge all my wheelsets on new cars BEFORE they hit the rails for the first time. I'm never disappointed in the little time I take checking stuff out first.
To each his own, but I'd rather fix problems before a derailment.
Run it out of the box and see what breaks? Sure, you can do that... it's just not my style.
