Electrical Solenoid Actuators

Can someone explain the following.

no greater than 10 watts continuous duty

Can I use an actuator that is 25 watts at a 10% duty, but drops below 10 watts at 100% duty, or must the maximum power be no greater than 10 watts?

Also, now I know this is probably very difficult to answer as it varies upon actuator design, but what range of forces could I expect to obtain using actuators that meet these requirements?

Many thanks

It is really hard for the inspectors to verify your promise to not run the solenoid at greater than x% duty cycle, and I therefore expect the intent is 10W @ 12V w/ 100% duty cycle. I would ask the GDC for clarification.
