Multiple car hard inquiries can count as one (De-duplication); 30 day buffer (score change delay)

Be aware: if coded correctly, any & all hard inquiries for car loans made within a 45 day window period should only penalize you as if they were one inquiry, except on EX2, where the window period is 14 days. This is called de-duplication, per Fico. Additionally, if coded correctly, automobile inquiries from the preceding 30 days are also ignored. You therefore, if coded correctly, have 30 days before a loan inquiry affects your fico scores AND all car loan inquiries within 45 days (14 days for EX2) from the first loan inquiry will not cause additional score loss. See the CSP at New Credit, Buffering and De-duplication for more details. Edited for clarity and understanding.

I got double pulled (accidentally, I hope) on EX for my financing and MF and EX both do show only "1" for recent HPs, but there are still 2 listed on my CRs. They were done within 2 days of each other. So bining does work! I still obviously have 2 recent HPs, but only 1 for scoring purposes, since coded correctly!

Binning is a separate concept this is de-duplication.

Never trust what MF shows for HPs! Remember last month I took 4 HPs on EX and it took weeks for MF to show me all of them. Meanwhile I got alerts galore from free CMS.

As worth mentioning is that the concept of de-duplication is in place due to individuals wanting to "rate shop" multiple banks when seeking an auto loan.

I have edited the first post to improve it and make it more understandable, you may want to reread it. Additionally I wanted to touch on the subject of binning. We have a perfect recent example. @Justaguy was kind enough to contribute datapoints to our inquiry thread where we are trying to determine the point cost for inquiries on each scorecard for each Version/Bureau. Anyway when he goes from 0 to 1 inquiry, or back to 0, it does not cost him any points on a clean/thick/mature/new revolver Scorecard. Why? I can’t recall if we have a diagram for this if not, we may need to make one, but every inquiry doesn’t cost you points. For instance in this situation, 1 inquiry or 0 inquiries are in the same bin, meaning whether the value is 0 or 1, it is not taking any points from him. it takes a second inquiry for him to lose points. The only other possible explanation I can theorize would be if he were maxed out in that category and had restricted or unusable points (I forget what term I thought I would use for that I’ll have to remember), and he has crossed it more than once without a point loss, however so I don’t think that’s the case. Same thing, there may be no point loss between five and six inquiries if they’re in the same bin. That just means there’s no difference between the two for scoring purposes.

In reading around this is a great theory but the results do not always hold water. As you mentioned there is an outlier score too!

Ok ... nice to know however, the real world does not necessarily really work that way! Speaking as of April 8 2024. Even the lender could not explain why there were more inquiries.
