Another oatmeal question

I do everything in grams. I put 2 cups of oatmeal and 9 cups of water into my crock pot ( as per the instructions just doubled) and figured it out this way

2 cups of dry oats is is 364 grams
for 40 grams there is 150 calories (assuming that is dry right?)

So 364 grams = 1,365 calories

When the oatmeal was done I weighed it complete and got 2275 grams so that would be 1365 calories...I plug that into MFP as if eating the whole pot...I won't I swear. Then just adjust it to what I actually eat.

What does a normal size bowl usually run for calories?
