I've used 1.5 Adox C-Tec kits so far, the first one for 9 120 films (same area as a 36 exposure 35mm film) and half (500ml) of the second one for 5 films, in all case in a Paterson tank holding 500ml and the films processed one by one.
I've concluded that you can definitely process 5 films in 500ml of solution without any obviously visible degradation of the colours of the processed film (there has got to be some degradation, but I can't see it!). So 3 films in 350ml should be OK.
The only caveat is that I process all my films in a batch of solution over 2-3 days (i.e. 5 films, one by one, in 500ml in 2-3 days) ... I don't let the working solutions stand around for more than 3 days.
Good technique! You're not letting the developer sit around and oxidize, Paterson tanks and the relatively gentle agitation doesn't aerate the developer like a Jobo. If Adox is using the same recipe as Tetenal this stuff will store (within reason) as a concentrate. The little Adox kits look great!
