CFP Winds
We use SITAGraphFlight. I compared two extremely similar CFP's one used by Emirates which is LIDO and one used by us which is SITA.
LIDO along with CFP winds give you a Sheer Rate table and I've found that wind projections are better.
Not that all flights are alike with winds being off, but they were several that gave us winds that weren't too accurate.
Whilst my guess would be that the CFP crossed its effective validity window and winds showed different, the MET reports we pick up forecast winds for 24 hours, which seemed very accurate when compared with the FMC, but the CFP again showed the difference.
