F4U-5 handling performance reports

[Metrallaroja]

Power Plant Chart (1952):

 

[mig-31bm]

Combat performance is estimated, normal and military are from flight tests. The date of the chart is from February 1949, I would have thought combat power results would have been available by then.

Is there any flight manual chart for F4U-5?. It would seem that the estimated performance is often very different from actual performance later on
For example:
Estimated performance

Later tested performance

Performance reduction from pre production calculations to aircraft in service were usually the norm.

Best to ask Mike Williams of WWII Aircraft Performance if any one knows he will.

How do you know that the later is flight tests without bomb racks and or rocket racks?

Later chart is taken from flight manual.
Interception profile doesnt include rack

Where it says that it doesnt include rack?
All I can see is that max speed is the same in all configurations which would indicate that in interception both rocket and bomb racks were used

but there is no rocket rack in interception profile

and the speed match with this

I estimate clean performance would be about 25 knots faster.
So about 640kph at SL and 780kph at 31000 feet!
