Does there need to be a gap in the market to produce a new film? Does it matter if they partnered with someone else to develop the film to their specifications?
The assumption that you reduce the processing time by 20% for rotation processing is wholly erroneous.
In general, assumptions, playing a central role as part of a critical, seemingly meticulous scientific and empirical study seems somewhat ironic

As someone above said unironically, not to nitpick this analysis, but there are an infinite number of uncontrolled and unaccounted for variables in your testing protocol...to avoid adding a source of variability to the analysis.
This is true (sometimes), the assumption 20% is the reduction amount is erroneous as apart's test has clearly shownTo be fair, reducing time for continuous agitation is standard, not an assumption.
Yes, i wish I had fresh film but I didn't. Sorry about that. Expired film is going to raise B+F and cause some speed loss, mostly. I can send you my Tri-X to see how much it differs from a fresh roll. My bet is, not enough to make a statistically significant difference.As someone above said unironically, not to nitpick this analysis, but there are an infinite number of uncontrolled and unaccounted for variables in your testing protocol
I am not saying its wrong, just that it might be correct for anyone in any other situation other than yours.
It would seem that the better alternative to ending up with years expired Trix that was never used and then sacrificed at the alter of an experiment that did not even involve the taking of one photo is to go out and take more pictures, on fresh film. If you buy fresh film, you support the industry that makes it. If you dont support it by buying more fresh film it will not stay around for much longer.
I am not sure if you're being serious here...

I suggest you overnight @aparat some fresh Tri-X and your recommendations for testing protocol instead of wasting time insulting the participants of this forum. Aparat is engaged in a good faith effort to understand your product, which can help your business. Do you not see this?I am not sure anyone here is

Each time I identified a post as the funniest one in this thread I was being serious as a heart attack.
Are there really any new black and white films in 2022? It appears that most everything out there is repackaged film from the same small group of surviving manufacturers (Kodak, Ilford/Kentmere, the Orwo/Shanghai/Innoviscoat/Agfa/Adox gestalt, Foma or, on a good day, Ferrannia). Or it's old aerial/surveillance stock from who-knows-where stuffed in a can.
There's obviously nothing wrong with CatLabs (or Film Photography Project) sticking a label on any one of these and selling it at a reasonable price, but it doesn't seem terribly exciting... certainly not exciting enough to warrant 13 pages of comments and counting.

Well said. I use the tables Eastman Kodak developed for XTOL in rotary processing. The time reduction 15%-20% is just a legend.
I don't have any reason to doubt the starting times for this film stated by Catlabs.
The final point IF WE DON'T BUY FILM AND PAPER IT'S NOT GOING TO BE AROUND. This is a huge deal. Paper is more at risk than film in the short term. But look at how quickly things changed with SinoPromise purchase of the Kodak color paper business.
I have a whole lot of frozen film, but I tend to buy new and use film within the expiration date (or nearly)
I love this forum, but there's so much hear say. Use the manufacturers suggested starting times, then adjust if needed. Maybe get a nice thermometer too.
There are some cars I wouldn't buy no matter what day of the week they were made. Undoubtedly someone will respond that it is people like me who are responsible for the demise of the car industry.I hope CatLabs includes a day of the week the film was made and packaged, if it is like buying a car we probably shouldn't buy film made on a Monday or Friday .
I can tell you that ISO get pretty legally minded if anyone puts a product on sale with a claim that it complies to an ISO standard without full documentation to prove it.
Which may be why Catlabs are saying "EI ISO 320" rather than "ISO 320".
