Bullet jump would be ojive to the lands measurement. Knowing it let's you know where your at loading wise. Weather your in the lands or jumping it really don't matter because your going to load it to where it shoots the best at anyway.

Seems that many people fear AI. Understanding AI can be encapsulated in the old phrase: garbage in, garbage out. It's all about the quality of the training program/data and the AI model (and there are a lot of different AI models aimed at solving a myriad of problems). When google depicted Nazis as black and Asian Vikings everyone knew that the model was trained with pure horseshite. It is better but there is no doubt that many AI models are trained with left leaning data. Those models often use algorithms like Random Forest that clusters data into specific groups and then selects the group that represents the highest probability correct answer. If the data being clustered is even tainted a little bit, then you know the results are tainted as well. Use the results with caution unless it is a model targeted and trained to solve modern problems in medicine or other scientific pursuits like development of new high tech materials.
They do, usually after you ask a question, just ask for the citations and it should give them. I use it for alot of college research. Sometimes the citations are not credible though, so you just gotta use your better judgement. Also, alot of people here saying it's left learning. Grok AI is Elon musk's baby, and I find it to be less left learning.
That being said, this isn't directed towards you but rather the thread. Its wild how forums bring out the hate in people. Just because somthing may lean left doesn't mean it's not useful. Hell probably 99 percent of the users on here; their doctors are no doubt left leaning, along with lawyers, and a plethora of other job sectors that are incredibly useful. The medical advancements we have seen through the last 30 years...most were left leaning people. Don't throw the baby out with the bath water.
AI is a great tool when used properly. It's based on human intelligence, so take that for what it's worth.
Do you remember the Internet 30 years ago? It was considered the misinformation highway.
How about your local gunshop before that? Memories of Joe Bob standing at the counter talking about great uncle Bubba, who said you don't need anything bigger than a 22 mag to kill a deer. Pretty sure that was called ZI, Zero Inteligence

It wasn't, until it had to be re-trained to be politically correct.
Doubtful. It takes less than half a watt to generate a query on ChatGPT.
Two hot water heaters would be closer to 9000 watts.

That's likely because many people are half a wit
A.I. Is a power hungry s.o.b. For some time now. the largest user of
processing power and the amount of cooling it takes in those Data
banks has been been bit coin mining. A.I. has more then surpassed
that. Micro soft and a few other concerns are in negotiation to bring
back and upgrade nuclear power plants that have been shut down.
Look at it this way.....People have to stop thinking in terms of mega
watts. It's now giga watts with terra watts soon after, and we don't
have the grid to support it.....Stay cool. The AC units being switched
on now is causing power to crash.

You said the OP, so I assumed that you were referencing ChatGPT.
Grok is supposedly more efficient, but I'm only stating what I have read in my limited research.
Most things that are electrified, are there to make life easier for humans. The goal of AI is to do the same. Just look at what it does in a web search. You can scroll through mountains of data that a Google search would give you in the past, or look at the answer the AI tool gives you today. It has definitely saved me time in my daily life.
First it needs to be understood that current state of AI, it's like garbage in - garbage out. We have to be carful with the questions being asked and have good sources to back up any answer given. With that said, I find this response by ChatGPT to be mostly true, but doesn't really address how much it can affect precision. While bullet jump can do all that is stated there, I find bullet jump not to be much of an effect on precision. . .particularly compared to the importance of seating depth. Too often, bullet jump is stated as though it's the same as seating depth. And that's become kind of a pet peeve of mine as I had to learn this difference the hard way (like I used to chase the lands).
For example, I've I read what's been published at the Precision Rifle Blog back in 2020. The data was very interesting to me, but the testing referring to "bullet jump" bothered me as there was no mention of the relationship to seating depth. This made it confusing to me as to what's really involved and having the most effect, bullet jump or seating depth.
Whether one focuses on bullet jump or seating depth, when one is changed, so is the other. But the things involved with with bullet jump (what's happening between the bullet and the lands) is very different from how the bullet sits in a case and what's happening as the bullet is released and exits the mouth of the case.
If you start by seating your bullet with a .010" jump and don't change the seating depth as the chamber's throat erodes by .030", you then have a .040" jump. And during that time, why has there been no change in performance of the cartridges. But, if you take that "seating depth" when you started at .010" jump and change the seating depth my .030" (meaning the bullet is now .030" deeper into the case) you find a significant change in the cartridges performance.
I've actually tested this in my .308 over 2,000 rounds fired where my throat eroded ~.033" having started with ~.010" jump" and good load that was developed. Having kept the seating depth and the load the same, wound up being .043" off the lands, I was still getting great results on target. Apparently, the amount of jump wasn't making any difference (yet, anyway). But when I change the seating depth by just a few thousandths (much less than .033"), changes in the cartridges performance become very obvious.
On several occasions, I've listened to top champion shooters (bench rest and F-Class) mention when they've done load development for a new barrel and found a powder, bullet and seating depth that works well, they don't change anything for the life of the barrel even though the throat erodes during the barrel's life time. Taking their comments like this along with that test I did, I can only conclude that bullet jump just can't be as important as seating depth. And the two should not be confused as being the same thing.
Asking ChatGPT questions remind me of the scene in I-Robot where Spooner is asking his little hand held AI that Dr Lanning left as a "bread crumb" a question and it responds: "I'm sorry, my responses are limited. You must ask the right question"

I don't fear artificial or any other kind of intelligence. The stuff falls off'a me like water off a duck.

jdI have been using Grock like you mentioned. I like it. Simple question and one simple answer. I really like it for finding things like local building codes and I have also used it to identify RCBS and Redding dies that were being sold by part number.

Isn't seating depth derived by the distance the bullet is jumped or jammed compared to the lands? Is seating depth just the amount it is into the lands?First it needs to be understood that current state of AI, it's like garbage in - garbage out.
