            "LockonTime = 41",
            "EnergyChargeRequire = 45"
          ]
        },
        {
          "type": "int",
          "comment": "Save Data Position???",
          "value": 1
        },
        {
          "type": "int",
          "comment": "Max Star Level",
          "value": 8
        },
        {
          "type": "float",
          "comment": "parameter_1 (p1)",
          "value": 0.5
        },
        {
          "type": "float",
          "comment": "parameter_2 (p2)",
          "value": 0.5
        }
      ]

If the setting type int is an odd number, such as for EnergyChargeRequired, then multiply p1 with (-1) because the value gets lower as star rating increases

result = BASE_VALUE * (p1 * (TARGET_LEVEL / 5)^p2 - p1 + 1)
