Although FLt Ops say the CFP corrections are good for Mandatory fuel, a few years back had a large 0FW drop and did the correction and established a new Final Req'd. Dispatch ran a new plan and the new plan had 300kgs more as Fuel Req'd. We were probably OK because of the 5% extra built into the mandatory, but I am now cautious about using the corrections on large 0FW drops on long sectors.
Sloppy Joe, as for what to do after airborne, I think you need to talk to a training god. Perhaps also ask him about the difference between "your" and "you're"
