I should know, but I don't where PAN F + comes in LI performance compared to our other film emulsions but I will speak to our technical service, they will advise me and I will let you know in the next day or so.

I've long had the idea that Pan-F had an issue in this regard, but perhaps not.
It's still an issue and Ilford reps have stated on the forum that so long as you develop within 3 months of shooting the film, you should have no worries.

It's one of those ... You deal with it because its such a great film.. Things IMHO

Also, why not just look at the times between HP5+ and FP4+ and half that time and subtract it from the FP4+ they are similar-ish films from the same company so the dev times should be a lot that much less of a stop from FP4+ to PanF+

It's a good starting point at least.

Good luck! I love it in Ilfsol 3 and Rodinal 1+50
