Default DME to Water ratio for starters and boil off

Say you need to brew a 1L starter.

Is the 1L measurement pre or post boil?

For example, You'd add 100 grams to a flask and fill up to 1L with water, then boil 15 minutes, then take note of the volume. In my experiences, after cooling down and whatnot, I'm left with somewhere around 750ml of starter.

Should I be adding extra water to ensure I end up with 1L?

Default

boil-off it typically calculated at 15% per hour. so unless you boil your starter for an hour - a silly thing to do - reaching 25% boil-off would be extreme.

i've thought of this question before, so i typically boil something like 1.05 liters, end up with 0.95 liters, then proceed to relax, not worry, and have a homebrew.
