Your welcome Marco. Development time is an interesting question though. Many describe Pt/Pd as developing "instantly" but consensus seems to be to leave the paper in the developer for two minutes. I don't think the precise development time matters much (I haven't seen any differences in the prints anyway) - the important thing is that sufficient developer soaks into the paper to develop the coating that's down in the fibres but not so much that you carry to much developer over into the next bath (and waste it).
