I always knew, and I always disclosed, that realism would be taken into consideration. This was in the original brief:
Then this clarification followed:
Since it was always disclosed that realism would be taken into account, I’m not sure why disclosure of the precise mechanism for considering realism would have made a difference in anyone’s engineering choices. In fact, I saw one of the finalists make a comment on Discord to the effect that “I always knew the rear double wishbones were going to kill me.”
I also don’t see how the upfront disclaimer about realism was somehow insufficient to put you on notice that realism would affect your score, or how it was any less precise than that provided in other challenges. For example, here’s the currently running QFC47:
Here’s the recently completed CSR162:
Similarly, here’s CSR161:
Here’s the thing that’s been bugging me about the reaction to this judging; I was actually more transparent about how the judging was conducted than most challenges I’ve seen and went out of my way to try to come up with scoring mechanisms that weren’t just my own subjective judgment, and yet because everyone has come to expect design/realism scoring to essentially rely on the host’s subjective judgment and the notion that I “modified entries” set off alarm bells, the different way I approached judging has clearly rubbed people the wrong way. Admittedly, it would have been better if I had identified the design/realism mechanisms upfront in the brief, but, as a first-time host, this was a learning process for me where I initially relied on simply imitating similarly vague realism/design rules in other contests without having a clear idea of how those factors would ultimately be applied. But exactly the same outcomes could have been reached if I’d simply written things up a different way that was more opaque about how realism/design was taken into consideration. And this whole conflagration started with a wildly mistaken comment suggesting that “the finalist cars needed changing to be finalists,” which I think framed and fed the concerns that I “modified entries.”
I know that at this point this competition is going to go down in everyone’s memory as the one where the judge did some crazy scoring scheme that “modified entries” and had a bunch of “twists” in the scoring, and that nothing I say can change that impression, no matter how much I think that’s a mischaracterization. I also know that there is nothing I can say that will make you agree with me or stop you from feeling like you were somehow robbed or cheated in this challenge. But realism was clearly identified as a discretionary factor from the start. Considering that I would have been within my rights to bin or severely penalize any entry that I found to be unrealistic, I think that applying relatively modest realism penalties to cars that reached the finals was absolutely a fair approach.
Ultimately, beyond simply not considering realism at all, it’s not clear to me what you would have considered a fair approach to considering realism, or what sort of disclaimer you would have needed to take more care with designing your car more realistically.
