Why are there Discrepancies in the Weight

[kmanning]

Hi

I don't know if any of you have noticed but I've noticed some discrepancies with the weight of the PIC 737-300. The discrepancies are from the 737 manual and the 737-300 aircraft.cfg. Here are the aircraft weight from the aircraft.cfg file:

 

Operating Empty Weight:              72,540 lbs
Maximum Taxi Weight:                135,500 lbs
Maximum Take-Off Weight:         135,000 lbs
Maximum Landing Weight:          114,000 lbs
Maximum Zero Fuel Weight:       106,500 lbs
Maximum Fuel Capacity:               35,579 lbs

 

Here are the aircraft weights from the manual: 

 

Max Taxi:          131,000 lbs

Max take-off:     130,000 lbs

Max Landing:    114,000 lbs

Max ZFW:         105,000 lbs

 

The max landing weights agree but the others no not agree, and they're using the exact same terms. So, why are there discrepancies here and which ones do I refer to when entering the information into the PFPX program?
