I've just been reading up on the theory behind Weak Sectors. I also came across some info on a trick called "weak sector amplification", aka "Amplify Weak Sectors". I want to have a go at implementing it myself - problem is, the info I've found boils down to the same thing - "This fixes weak sectors by adding errors to them". No technical info, nothing like that.
Does anyone know how AWS works or - even better - how to implement it?
