Questions re Palm & film curves |

I’m new to Expo Dev and will be using it for Platinum/Palladium printing (Paper ES 1.4 upwards). Being new I have a few questions:
1 Some of the sample film curves when loaded into the Palm handheld computer show the development as D76(ID11). Does this mean these two developers produce the same results? I have just made a set of film curves for FP4+ in ID11 diluted 1+0 but do not know the extent to which I can compare the results with the D76 sample curves.
2 What reciprocity data do I insert when converting my FP4+ and ID11 film curves into xdf files for the Palm? Does the reciprocity value alters if one dilutes the developer e.g. from 1+0 to 1+1?
3 If the focal length input screen is only required for bellows and DOF calculations presumably it makes no difference if I am using my 10*8 or 5*4 camera- in other words I do not have to convert e.g. a 300mm focal length for a 10*8 to 150mm, the 5*4 equivalent and insert this value?
4 When metering a scene under the incident or zone method, is it necessary to set the meter at ISO 100? The date entry screen help screen says for incident metering “Lo EV/Hi EV: Values given by your incident light meter (ISO set at 100) for shadow and highlight”. Does the same apply when using the zone method?
I would be grateful to receive advice on these issues. Apart from that I have to say I am really looking forward to trying out ExpoDev in the field.
Many thanks
W Hume
