Preview and notes of my Caffenol developments

I thought to publish this list of my developments to keep track of what happened during each session. Every development is usually a kind of surprise, so generally when I process I try to write down some information that are relevant. The formula that I generally use has been created and published by Adrian Cousins. It is:
FD (1liter): 100g sodium carbonate, 40g ascorbic acid, 60g coffee, 16 sodium hydroxide, 2g potassium bromide;
SD: the same, with only difference to reduce s.h. to 9,5g;
bleach: 1l hydrogen peroxide 9% and 28ml acetic acid, after the first 100 feet I usually add 2ml;
fixer: 200ml Ilford Rapid and 800ml water;
photo-flo: 5ml of Kodak professional photo-flo wetting agent in 1liter of water.
The temperature of FD, SD and bleach is generally 24°. The lamp that I usually I use for the second exposure is 70 watt.

Development 44, 3/3, date: 20/04/20, film: Fomapan, camera: Bolex; Erice, Paceco
FD (Ilford + 0,5 sodium thiosulphate) 12:00 at 22°; wash 5:00 4 risciaqui; bleach 21°; wash 2°; SD 21°
Piccolo incidente: ho perso circa 100 ml di SD. Ho recuperato quindi quei 100ml dal dev 2g di Thio (quindi 0,2g). Non credo cambi tanto.
Risultato: Vermetti. Sospetto: vermetti potrebbero essere dall'SD con Thio. O anche dai 22° (e non 21°) di FD.

22/04/20
Nota per il prossimo sviluppo con Ilford.
FD 100ml sviluppatore Ilford + 900 water bollita + 0,4 thio
SD assolutamente NO thio
E' importante che SD non sia forte.

FD (Ilford + 0,5 sodium thiosulphate) 12:00 at 21° (temperatura naturale); wash 5:00 4 washes; bleach 5:00 21°, wash 2; SE 2+2; SD 5:00 at 21°; wash 7:50, fixer 7. During SE white is the part with emulsion, dark without emulsion.

During the the SE the film is white instead of green. It may be because of the reduction of agitation? Or less bleach timing? or minor temperature?
