Using the calculatorhoping somebody can help me here,
I brewed this @ 23L with 1kg of brewing sugar and about 250g of DME.
FG: 0.002 (seems a bit low?)
when i asked the other half what OG she recorded down on brew day she came at me with 1.080
obviously that is an insane OG, and I remember vaguely seeing the hydrometer being in the colour coded section and not bobbing all the way out of the measuring cylinder... im thinking she meant 1.008.. putting this at less than 1%abv
im going to check the hydrometer for accuracy. but can anybody tell me what their OG was if they did something close to my recipe?
the little taster i had when measuring the OG certainly tasted a lot more alcoholic than 0.79%

gives your OG at 1.040, which looks about right.
You cannot have a beer SG of 0.002, so your reading is incorrect.
I suggest you read your hydrometer 'how to use' instructions and/or following
How to measure Specific Gravity using a Homebrew Hydrometer - The HomeBrew Forum
and perhaps also test your hydrometer in clean water at about 20*C when it should read 1.000.
