When ever I refer to people not understanding the economies of scale in making film at the scale that is required to put forth a quality product, the above puts it into full perspective. The people who are often asking for films gone by *highly* overestimate the actual interest...and they take it personally that their chosen product has been discontinued.
I certainly have my hordes of cool discontinued films, but I really choose to use the most stable products out there that meet my needs in order to get into a rhythm I can count on.
Thanks for putting it this way PE, maybe it will sway a few to move on and support the great products we have left....and write a thread about how thankful they are to still have them.
Your numbers mau not fully reflect the fact that some participants wouldn't use K even if it did resurect from the grave.
...which failed due to no demand...
KA will succeed because they have found a way to make less film, more profitably.

Have fun. I'm not going to do it and bore you.

My wife and I are celebrating a quiet Christmas Eve listening to music and reading. Some of our kids and grandkids were over this afternoon and we will see more tomorrow.
But, while sitting here I have been reviewing in my mind the procedures for making Kodachrome (as far as I know them) and my mind boggles. I have considered writing down my thoughts but it would take a several page word document from the start to finish. If I did that, I wonder how many would be interested....
Here is an outline.
1. Make 9 emulsions, 3 each for R/G/B.
2. Test the 9 emulsions alone and together to see if they meet specs.
3. Sensitize with Gold and Sulfur. See if they meet specs
4. Coat 3 sets of 3 emulsions to test as R and G and B
5. Spectrally sensitize and retest and do a short keeping test
6. Coat a short narrow test of a multilayer and test
7. If all tests are passed then go for it.
Chemicals needed, Silver Nitrate, Sodium Bromide, Potassium Iodide, Gelatin (probably 2 - 9 types), 3 sensitizing dyes minimum, TAI preservative, 3 specific preservatives, hardener, and of course access to a processing line for testing. This includes CD3, Cd6, 3 couplers, lots of other organics, alkali and an MQ or PQ developer.
You need a team of technical people for making, coating and testing. Not the same people. They have to test for grain, sharpness and color reproduction as well as speed.
This document would be long and hard to read.
Have fun. I'm not going to do it and bore you. Get some friends to join you and post here instead.

Sigh..., reading about chemicals used for the production, it almost makes me want to get away from film.
Be careful about the discussion, it could lead to falling interests among the younger generation who wants to experience film.
That is an uncomfortable truth that many of us has grappled with for many years.
I can't imagine why reading about the complexity if Kodachrome would discourage anyone from using chromogenic materials much less far simmer black and white ones.
I hope you're having a good holiday Brian, and that Santa didn't suffer the same fate as UPS
