Model 3 does more than 429 Kw from the battery. I have seen as much as 448 Kw with a fully optimized battery.
I can make the car at 16% SOC perform like the same car at 89% SOC just by changing the battery temperature.
Here are two max discharge values at different temperatures and SOC. 365 KW is ~490 HP.
You need to go out again and look for the actual delivered battery power.
A max discharge is a theoretical value.
The BMS might allow for 460kW for the sake of the battery, but the car limits the power to 428-430kW from the battery.
At all other values but the upper power limit, the output voltage from the battery will be too low to make the motor deliver the rated power.
Do the homework again and come back with confirmed numbers of actual battery power delivered
