Flight Planning Systems LIDO/Jeppesen

[GroupWatcher]

Good afternoon,

have a general question ref. acuracy for flight planning systems. How does Jeppesen (JAS or OnSight) compare to LIDO in terms of fuel and enroute time acuracy (I mean comparing the flight plan to the actual flight burn/time).

Also would be curious as of how frequently the actual winds are being updated in both systems and whether a "buffer" (fuel and/or time) are figured into the flight plans.

Thanks
