Does anyone know what the thrust-to-weight ratio is for the Airbus A330-900neo?

I'm getting different numbers when I try to calculate this for myself.

The thrust-to-weight ratio is not a single number because both thrust and weight vary throughout a flight:

The thrust-to-weight ratio varies continually during a flight. Thrust varies with throttle setting, airspeed, altitude and air temperature. Weight varies with fuel burn and payload changes. For aircraft, the quoted thrust-to-weight ratio is often the maximum static thrust at sea level divided by the maximum takeoff weight.

(Wikipedia: Thrust-to-weight ratio)

For standard sea level conditions with maximum takeoff thrust and at maximum takeoff weight, we would get the following numbers (source) for the A330-900:

Thrust / Engine Total Thrust Mass Weight Thrust-to-weight ratio
324 kN 648 kN 251 t 2462 kN 0.263
