That's the general problem with recipes that don't list technical
parameters like sg for different steps - 2 weeks can lead to very
diferent things, depending on the yeast used, temperature, nutrients,
starting sg. etc.
It's possible the raisins release the sugar slowly over the time of
the fermentation and that's why the time in primary is longer? - just
guessing.
I'd transfer ASAP if you're at 0.990 - that's dry.
