I always use raw chemical for preparations of solutions.
Reversible process b & w you should read densities of film.
At least fog density and high density.
From memory, the Kodak Double X (as reversal process b & w) fog was ~ 0.3 and maximum density was ~ 2.6.
If you look at the characteristic curve of KODAK TRI-X 7266 is not
as rich in density curve as a negative film.
Again, I think better results can be obtained on films with small fog.
I have not worked with KODAK TRI-X.
Do you mean that KODAK TRI-X 7266 is lower contrast than a Tri-X negative film? That doesn't make Super 8 Tri-X sound too good from my experiences with Tri-X 35mm.
As an added comment, TriX film is quite a normal film and should reverse just fine, and Kodak once sold a universal reversal kit with times for a wide variety of their films. So, one process can cover a multitude of films.
you can see that mrred has used powder Dektol at 1+1 and 1+2 on many films with great success (i have seen the results). The Dektol liquid (that i use) is already 5 times the strength of Dektol stock from powder, so I am suing it at 1+9 or at the stronger 1+5 to shorten dev times.
It's not that I don't want to hear it but rather that if Dektol will only work at 10 times the normal concentration used to successfully reverse develop other films, that maybe it is the wrong one for Tri-X. Then maybe I have nothing to lose except ruling dev concentration out.
I'm not panicked, just frustrated that I've wasted huge amounts of time trying to re-invent a wheel that someone has already made perfectly well.

j' ai utliser le dektol comme ça : Dektol 200ml : eau 400ml + 30g de Sodium Sulfite anhydre
dévellopement 5 min à 20°c
rincage 2 min
blanchiment 1min 30 (Solution A : 500ml eau, 32 ml Acide sulfurique Solution B : 500ml eau, 1,5g permanganate de potasse)
rincage 1 min
clarification 2min (105g of Sodium Sulfite pour 1l eau)
rincage 2 min
Expositon à 100 watt 2 min
2 ème dévellopement 5 min à 20°c
Rincage 1 min
Fixateur 2 min (1+8 superfix plus Tetenal)
Rincage 2 min
Bain eau distillée 2 min
