Come out to ITR and prove it! Color me very skeptical.

Chris-
it goes like this:stock hp x IT factor x class factor = base weight
(Borgward Special: 160hp * 1.25 = 200 * 12.9 = 2580 base weight).
base weight * percentage = adder. (2580 x5.56% = 142.)
So the Borgward, barring any other adders would weigh 2438
other adders come off that number, or get added to that number.
Clearer?
Thanks Jake. It is applied as a % on the individual car's process weight (for all factors except driveline type). This is a good evolutionary step.
We think so. We like that it is based in real world science, and that it is more granular, and it is very repeatable.
It's taken some work, but these are the kinds of thing s we've been cooking. I consider it "The Process 2.0". It is attempting to fine tune what was already a good thing, remove either real subjectivity or the appearance of subjectivity, increase consistency, and make it more robust going forward.
More to come.
If I'm following the first question correctly, we are applying the percentage for each class to determine how much to take off of each FWD car run through the new(est) process. We used a class average IT HP as part of the process for figuring out what those percentages should be.
I'm not following the second question, I'm afraid.

EDIT - and I should add that some of you might see your influences in what we've decided to do. THANK YOU all for that.
Good point. Thanks.
As Kirk mentioned earlier, it's still a topic of discussion about what to do about existing listings when the process changes (and these 'refinements' really are changes.) If we manage to reassign weights, we'll take the axle into account for those listings.
Please run the 1.8 ITA Miatas thru your new and improved process. :D
I think it is a good idea to hold off on any more re-classing until you guys have the whole thing hammered out since I know you guys have said there are a few more things you are trying to lock down, so future ITAC's will be able to follow exactly what you guys did.
Interesting the GSR would be the exact same weight before adders?
I am pretty sure the GSR was run through the process and the subtractor was used in calculating its present weight (or at least -100 lbs, which isn't far off from what it would get using the new formula).
We go around and around about that, Mike - it's a real puzzle.
We decided to do a couple of new listings last night even though we are still working on a final aspect or two of the new system, but only after estimating that they would come out pretty much the same even if/when we change what we're looking at changing. On the other hand, we have a basketful of other reviews that we want to be sure we do with everything in place, because we think revised practices ARE likely to influence the outcome.
We feel like we can't simply stop doing our business just because we're working on HOW we do it, but it's a balance that we make decisions about.

There may be more surprises for GSR owners....if they are good boys and Santa is nice. ;)
Regarding cars "in the works", (that is, cars we have requests to reprocess) ...we've held back on those cars that have characteristics that might be affected by our refinements. Some cars however don't, and those we are trying to do.
And just to reiterate what Kirk mentioned. Some cars might not get what the owners feel they deserve, and others might get a tiny gift. None of this is F1 level science. We're not trying to balance every car in every class on the head of the pin. There will be winners and losers.
BUT, we're hoping the range between the winners and the losers is kept in check, and we want, more than anything, to be consistent.
We want you guys to have faith that your car got a fair shake, and it was the same shake as a car a year ago got, and one a year from now will get. There may be things intrinsic to certain models that result in better race cars, but we hope our system mitigates those to manageable levels.
On edit: Looks like Kirk has made my point redundant..he types faster!
