What is the rule on sharing my own spreadsheets for yardage now?

The main distinction ussually comes down to wheather you're pushing a product for profit or just sharing a shortcut you use in the field. Those app developers were clogging up the works with flashy interfaces for stuff we can do with a pencil and a scrap of 2x4. When someone drops a link to a "free trial" that eventually asks for a credit card or an email login, that's what gets the mods' blood boiling.

Sharing a **basic math template** or a slump calculator you built yourself is generaly viewed differently by the guys who actualy pour for a living. If someone is struggling with their waste percentages on a big slab, giving them a formula or a quick sheet is just being a good neighbor. It’s the subscription model and the fake market research that turned this place into a sales floor. Most of us just want to talk about how to keep the mix from kicking too fast in ninety-degree heat without being sold a project management suite. But you have to be careful how you present it. If you start calling it a "proprietary tool" or acting like you're a tech mogul, you might catch a ban. Just post the raw logic or the file as a helpful resource directly in the comments when someone asks. The AI junk is easy to spot because it's usually generic and doesn't account for real-world variables like humidity or aggregate size. Your field-tested stuff actually has value because it comes from experience. As long as you aren't trying to harvest data or sell a "Pro Version" in six months, you shold be fine. We’ve all got our own little tricks and spreadsheets for estimating yardage and keeping the trucks on schedule. The ban is for the people who treat the trade like an untapped market for their software instead of a craft. Keep it simple and keep it about the concrete work itself.

That's a relief. I'm just starting out and honestly, the spam was making me think I needed some expensive subscription just to figure out my first slab. It’s hard enough figuring out the right mix without being hounded by "AI assistants."

I've been keeping a handwritten notebook of what works on diffrent jobs. If I ever want to share a specific ratio or a shortcut I found for checking form levelness, should I just stick to text only? I’d hate for a helpful tip to get flagged just because it looks like one of those "optimization tools" the mods are hunting down.

Most of those apps fail becuase they're built by guys who've never even held a screed. They don't get that a mix behaves differently when the humidity spikes or the truck is delayed. A simple spreadsheet you made to handle your own waste is just a digital version of a cheat sheet we used to keep in our pockets.

As long as you aren't asking for a login, it's just helpful info. If your file helps a guy avoid being short half a yard on a hot Friday afternoon, it’s got more value than any 'pro' tool made in an office.

The 'market research' guys were the absolute worst. I had one clown DMing me about my 'pain points' with rebar scheduling while I was literally standing in a trench. If your calculator doesn't come with a 20-minute survey or a request for my email, you're fine. We can tell when someone actualy knows how a truck flows versus a tech guy looking for a payout.

I’ve noticed alot of those paid tools don't even have a toggle for different aggregate sizes, which completly messes up your void ratio when you're trying to estimate paste requirements. If your Excel sheet accounts for things like absorption rates of the stone or specific slump-loss timings, that’s actual technical knowledge, not a sales pitch.

As long as you aren’t hiding the math behind a paywall, you’re adding to the collective knowledge base. It’s the difference between showing someone how to read a tape measure and trying to sell them a $500 'smart' ruler that requires a monthly firmware update.
