This is not an attempt to start a fight but what do others have to say about success or otherwise of Fuji paper being processed at room temp? Do all your experiences match polyglot? It may be that Fuji does not work at room temp. I don't know as I too used some old sheets of Kodak but it is important given that Fuji is the only paper obtainable in sheets and unless you want to buy rolls and cut your own then newcomers to RA4 might have to consider buying a heat controlled Nova or Jobo.
OK tray processing at 35C is not impossible but it is not something I'd want to do without heated platforms for the trays and if this is necessary then you might as well spend money on a more convenient system such as a Jobo or Nova
