Jorge, as you know I also use Rodinal, 1 shot and 1:100 stand or semi stand. I will send you the negative we have been discussing and let you get an impression from it if you want. Send me a PM and I will try to post it this week. Just for additional info, when doing roll film, I have made up 1L of developer (dil. 1+100) and used only part of it for one roll, then after about an 45-60 min started the next roll, have not noticed any difference, but that does not mean much - doubt I am as aware of my negs as you are.
