So have we a consensus that about 3 months is the max time for exposed but undeveloped Pan F before some deterioration in latent image is experienced or have we others here who have left their Pan F for longer without deterioration?

If Pan F is unique in exhibiting this phenomenon in the Ilford range, I wonder what makes it this way. I have twice been on the Ilford tour and there was nothing I recall being said about its emulsion or production that even hinted at this problem.

Of course some might say that Ilford wouldn't reveal this any way and that's why nothing was said and indeed according to one poster Ilford has hinted that such a problem exists or has even stated it( Simon Galley being mentioned)
