I sometimes do color wet printing (RA4) and I get more or less good colors.
The reason why I do at 22ºC is just because is quicker than heating the developer up to 38°C.

Can I take it that you have never got a colour cross-over problem with wet RA4 printing from film developed at 22 degrees C?

If I may be so bold as to state my conclusions from the range of statements in this whole thread: 1. Depending on elerion's reply, there may be the possibility of colour cross-over at less than 38C which will be difficult or impossible to cure with wet printing RA4 but can be cured using the hybrid route. Thus hybrid users need not concern themselves with the need to develop at 38C. Wet printers may suffer from crossover unless film is developed at 38C but to the best of my knowledge no-one has yet shown examples of the difference between 22C film and 38C film. It remains a theoretical problem based on actual evidence

Is this a fair summation of what has emerged so far?

I've never developed film at 22ºC. Just simple developer tests with totally overexposed tiny strip of film.
I usually develop film at 30ºC or sometimes, if ambient temperature is high enough, at 38ºC.
All RA4 prints I've done so far were from 30ºC and 32ºC developed-film.
Tetenal Kit manual states precise times for 30ºC, so I stick to it.
I sometimes developed at 32ºC, interpolating time, and the results seem nice too.
I didn't see any crossover, or at least I'm not aware of it.

I also scanned most of the images from these films, and colors come out well enough, with high fidelity, even if no digital adjustments are done.
