Jim's Beer Kit

I was reading this last week whilst drinking a beer that was only 2 weeks from grain to glass, so was of the opinion that with good temperature control and force carbonating your beer would be drinkable on time.
I'm thinking your stag do was this weekend so how did the beer turn out?

I would like to give something like this a go, but with 95% pale malt, 5% chocolate malt and 11% invert no 3 sugar, something does not quite add up I think?

Also if using a combination of golden syrup and black treacle to replace the invert no3 do you know the percentages of each to use?
