hi LAG
with caffenol, like most developers developer times are variable. the times posted, even by the companies
that manufacturer the developers and websites that have large charts,
are starting points. its obvious cameras' shutters are not all the same or even accurate, its accurate not
everyone measures chemicals the same and it is obvious they don't agitate the same either.
developing long expired film can be tricky, and it seems a lot of people ask the same or similar questions
( i can't even count how many times i have read questions about developers
times and temperatures for expired film ).
i imagine the OP figured he ( or she ? ) would use stand development because a lot of people think
( wrongly or rightly ) it is a cure-all for all. a lot of people believe
it is the best, the most funnest, and easiest way to process film. usually they ( these people )
ask questions about stand development and get a lot of of cheerleading posts
saying it is a fantastic way of developing film, and then and equal amount of people suggesting
it is good for some situations, usually not many.
regarding caffenol ... i am kind of an outlier with the caffenol developer squad. while i know
i would get great negatives without using a little straight print developer
as an "addition" they usually would have a weird almost pyroesque fog/shimmer to them,
i spent years battling weak/uncontrasty xtol film, and i spent 7 previous years ( maybe more )
experimenting
with ansco 130 processing film every imaginable way, and since at one time i had 6 gallons of
ansco 130 i started experimenting with adding it to my caffenol and it worked both as a preservative
and it fixed my weak-vit c negative fears caffenol c re-animated ... BUT caffenol tends to make foggy
stainy film, something probably not the best for old expired maybe poorly stored
film that is already foggy

both dektol and ansco 130 have potassium bromide in them which are
great for fog reduction. they can both be used for film processing
using the 1:dilution for dilution minutes ( like 1: 5 for 5 minutes for example ).
i pretty much only expose and process expired film which i use these developers for ..
not 40 - 60 years expired but still
like with everything YMMV
have fun!
