It doesn't seem to matter much whether the engine is hot or cold, but maybe a little worse when hot. It is a 307 with a TH350. Cold start-up pressure is 40-45, warmed up it is about 25. What would cause this to happen? Would it be a bad thrust bearing maybe, and above idle the oil pump is able to make up the loss of pressure?
