Any single inquiry impact > 21 points on FICO 8?

[Thomas_Thumb]

A majority of MyFico posts I have seen relating to cards reporting balances view both % of cards and number of accounts reporting as scoring factors. Many advise having 3 cards so that when AZE1 is practiced less than 50% report. Thin, card only, files have been observed to be more sensitive to changes in utilization and cards reporting.

In the past, at different times, I received HPs for CLIs. Twice I had one on EQ and once on TU. Never EX. I had 6 cards, 1 was an AU. Month to month number of cards reporting balances varied between 2 of 6 and 6 of 6.

My EQ mortgage score dropped noticeably at 5 of 6 reporting(83%) and substantially at 6 of 6 (100%). TU and EX score changes were very muted by comparison. However, after taking a HP on TU, that Fico score started dropping noticeably at 5, 83%, reporting and substantially at 100%.

That prompted me to relook at EQ score changes with/without a HP relative to % cards reporting. EQ had always been the most reactive to % reporting balances but, did HPs play a role. After seeing the change in TU (with HP present), I took a closer look.

End of day my conclusion was yes, the HP influenced level of response on EQ and TU to % of cards reporting balances. The difference was substantial at 100%. I posted on this and presented separate charts for TU score vs cards with balances with/without HP.

I had an open mortgage at the time and we know how Fico 8 likes to see open installment loans. Those scores were pegged at 850 so no impact changing % cards with balances. Now, without an open loan, my EQ and TU fluctuate 10 points depending on # or % of cards reporting small balances. 

A single card file with no loan (open or closed) likely reacts more strongly to % of cards with balances. For a single card file, any reported balance, equates to 100% of cards.

Could a HP affect the response penalty for 100% reporting balances? If so,  offset would remain consistent as long as any balance is reported and the HP is counted.

Of course, the above is speculative as is a 21 point HP.

You're really struggling with this one @Thomas_Thumb, so I'm going to go ahead and help you out with it since it's clear this conversation is just going to continue to drag on and on.

The only difference between the two profiles is the hard inquiry. Both have 1 account. The same utilization. The same 100% AWB. One TU report has the hard inquiry present, the other TU report does not. 771 vs 750. 21 points. 1 hard inquiry being the difference.

And a year later? Super simple. You grab a FICO 8 score pull mid-month (when no aging metrics can change, AFTER they have already crossed the 1 year mark) the day before the hard inquiry reaches 365 days in age. The score is X. You grab another score pull 2 days later after the HP becomes unscoreable. There are no other report data changes in between. The score is X+21. 

It's a super simple, clean test. You may not know me very well, but you know BM and Cassie and know that they wouldn't put information out there that isn't clean. And as I said previously, this same result has been replicated multiple times since, with the same result.

Where is the EX and EQ data for the files mentioned?

[BrutalBodyShots]

The same place it was the last time you asked, @Thomas_Thumb. 

You don't need data from "EX or EQ" if your goal is to determine the scoring impact of an isolated data point related to TransUnion data.

If I want to know the impact of a collection falling off of my TransUnion report to my TransUnion FICO 8 score, do I need to see the EX & EQ data?

If I want to know the impact of crossing the 29.5% threshold point for aggregate utilization on my TransUnion FICO 8 score, do I need to see the EX & EX data?

If I want to know the impact of the 78m threshold point for AAoA on my TransUnion FICO 8 score, do I need to see the EX & EQ data?

The answer to all of the above is "NO." 

The same exact way if my goal is to determine the impact of a hard inquiry to my TU8 score, I need to only look at the TransUnion data.

A TU hard inquiry reaches 365 days of age on January 20. You pull a TU8 score on Jan 19 and another on Jan 21. The difference is X and *no other report data* has changed. Do I need "EX and EQ data" to determine the scoring impact of the hard inquiry on my TransUnion report and TransUnion score?

Again, the answer is "NO."

It's odd (and telling) that you keep pivoting/deflecting to EX & EQ data, but it's nothing more than a smokescreen attempt to detract from the actual data that does matter here.

[Thomas_Thumb]

Then, your conclusion remains questionable.

[BrutalBodyShots]

It doesn't, because your EX and EQ data have zero bearing on a score generated using TU data. There's nothing questionable in the least. I know it's easier for you to keep saying that rather than to focus on the actual facts though.

If one has a 30D late payment come off their TU report that isn't present on their EX/EQ reports, why on earth would they need to look at their EX/EQ reports to know the impact on TU8? Super simple answer - they wouldn't.

This hard inquiry example is absolutely no different.
