I'm a data nerd. I love data on all things, and doing meta analysis. It's just hobbyistic - I'm not a mathematician - but I have a lot of fun doing it, and sometimes I find insight I appreciate, be it because it's meaningful or because it's beautiful. There's a bit of a backstory to this; if you're only interested in my actual question and list, skip until I do a double line break:

-

I have an exhaustive inventory of all my films (about 450), many of which are horror, some of which are found footage, my favourite subgenre. My inventory spreadsheet includes a lot of data points already, like runtime, type of disc, Rottentomatoes' score and production country, and now I wanted to add a budget column.
Remembering how long populating the production country column took, and knowing how LLMs work, I thought that might be a good job for it: Prompt it with the full list, accumulate budget numbers, populate a CSV, and request an additional column for confidence. Double check the ones marked as confirmed, and then decide whether to keep the estimates for the sake of a completed data set, or just skip those movies forever for the sake of integrity.
Unfortunately, I forgot that LLMs love to lie (or rather, underestimated how often and easily they do it), and even when I prompt it to only use my provided list, it quickly disintegrates into generating movie titles by speculation. Fortunately, this is easy to see through since I know which movies I own, but the same inaccuracy must be assumed for the budget numbers. At that point, I invested more time into engaging with ChatGPT than populating the spreadsheet myself would've taken, but it was a great opportunity to reverse-engineer ChatGPT's inner logic structure, so I continued from there, more for the sake of probing the LLM than creating my actual list.

-

At this point, I still want to actually create this spreadsheet, and I'm particularly curious about low budget horror and found footage horror, subsections of the film industry whose budgets are notoriously underreported, with some very popular exceptions. I probed several franchises and examples more deliberately and prompted a bottom-up approach to get the reasoning for the estimates, and created a list that's a combination of officially reported numbers and more realistic estimates. The attached screenshot is the subsection of that list that's found footage films.

I would like to employ the help of swarm intelligence:

- Are there budgets marked as confirmed on here that anybody knows is falsely reported?

- Are there budgets marked as estimated that have officially reported numbers?

- Are there reported numbers that are false?

- And are there opinions about the estimates? 

I'm trying to get to the highest possible, and reasonable, amount of realism, knowing it's impossible to actually achieve that. Part of the fun with this for me is that it's hard and complicated; I hope there are people on here that feel similarly about problem solving! And if not, I know there are people with broad knowledge on here that can help out anyway. Thanks in advance either way!

Trying to assemble a spreadsheet for budgets of all of my films with the help of a LLM, and running into its limits. Need help double checking figures and estimates.
