Wow, am I reading that right?


If all contacts are made using a power of 5 Watts or less, but the power source is from a commercial main or from a motor-driven generator, the power multiplier is 2.


and


If any or all contacts are made using an output power up to 150 Watts or less, the power multiplier is 2

That can't be right.

If all contacts are made using a power of 5 Watts or less, but the power source is from a commercial main or from a motor-driven generator, the power multiplier is 2. If batteries are charged during the Field Day period using commercial mains or a motor-driven generator the power multiplier is 2 (two). 7.2.3. If any or all contacts are made using an output power up to 150 Watts or less, the power multiplier is 2 (two). 7.2.4. If any or all contacts are made using an output power greater than 150 Watts, the power multiplier is 1 (one). 7.2.5. The power multiplier for an entry is determined by the maximum output power used by any transmitter used to complete any contact during the event. (Example: a group has one QRP station running 3 Watts and a second station running 100 Watts, the power multiplier of 2 applies to all contacts made by the entire operation).
