When to weigh potatoes?

If I take a 500 gram raw sweet potato and microwave it for 10 minutes, it comes out weighing 400 grams. Plugging that into MyFitnessPal, that's a difference of over 85 calories. The microwave gets pretty steamy so I'm assuming it's all water that's being lost, but which weight am I supposed to count?

    500 g if you search for "raw sweet potato", or 400 g if you search for "steamed sweet potato".

    The part of the potato that left was the non-caloric water due to microwaving. It did not lose any calories, just water.

    Log the raw weight as it will be the most accurate measure that you can get. Cooking things doesn't change their caloric density unless you add or subtract from them, cook in oil, etc.

    Use the USDA entry that matches its cooked or uncooked state.

    I didn't steam the potato.

    Log the raw weight - be sure to choose an entry for raw sweet potato.
