Bracketing exposures on film remains an extension of not fully understanding the limitations_abilities of ALL the photographic materials and process involved with print making and the image maker's print goals. This included having and knowing how what tools are required and using them to the best of their abilities and capabilities.
To gain understanding and behavior of photographic materials demands testing ... as was the beginning of this LFF "discussion".
In the specific case of color transparency film, this previous post examples how this was done decades ago as a common daily event.

Once actual film speed to produce a given density and overall color balance of the color transparency film has been measured and determined, these metrics become the basis for how that specific lot/batch of film will be exposed coupled to the limits of the dynamic range of color transparency film. Much identical applies to B&W films like Kodak TMX... Don't believe for a moment B&W film is more forgiving than color.. to achieve GOOD print results demands the same degree of attention to testing as color transparency film. Doing less results in wasting photographic materials, YOUR time (not replaceable once spent), YOUR resources and much more..
The working "pro" foto industry back then developed specific tools to stop the practice of bracketing film exposures by applying science and technology to remove the need for bracketing exposures which is in many ways guessing to deal with uncertainty.

It is much about fully understanding the dynamic range and Latitude of a specific photographic material. It is why and how the Sinar ground glass metering system came about.. This is also why properly using a GOOD accurate/precise spot meter can work wonders to eliminate bracketing exposures.. to about zero.

Back in them days of color transparency film centric images for color printing and other means of printed materials, Fotographers that bracketed their film exposures lots were considered incompetent and less in many ways as long experienced working "pro" photographers considered exposure bracketing a serious wast of film and much more.. This discipline of making each and every frame or sheet of film exposed count seems lost today.. due to the non-cost of digital image making.. but appears to have been some what re-discovered by folks new to film image making.
Take the time to read the complete Sinar Info# 31 on Contrast Control as it directly applies to this specific discussion and speaks directly to the belief bracketing exposures is needed.. the .jpg versions to follow..

As for, "Weeks often months can go by before I shoot a shot.".. Non-option for photographers that make images to put food on their table, roof over their head and meeting the demands of daily life and living... This is one of the differences between some of the very best artistic commercial photographers back in the day -vs- hobbyist or artist wanna be..
