May have to start all over again

[WildFlower]

I can't comment on the Laptop speakers but I do know that stage 4 was where I hit a lull in the Alpha set. If you keep using it a while longer, perhaps into stage 5, you may just have a 'lightbulb' moment where everything clicks and you notice the changes. If it wasn't for me approaching people like crazy during stage 4 I'd have probably concluded that the effects of the sub on myself where also declining and had halted. I had definitely seen many effects prior to then but perhaps had become totally accustom to them by stage 4? Whatever it was everything was internalised and I felt on a bit of a plateau. This could well be what you are experiencing, or your speakers could well be letting you down. I say give it a few weeks - on a different par of speakers - though before starting again.
