Use this to calculate priming rates.

Irrespective of what the instructions may or may not suggest 8 g table sugar per litre gives 2.9 volumes which is far too much for a stout and for that matter many other beers.
I would be aiming for one tsp sugar per litre (about 4.5g/litre) which will give about 2 volumes, and for lagers and AIPAs etc 1.5tsp per litre giving about 2.5 volumes. Others may do it differently.
