from what i hear from community the speed boost multiplyer works as in if u buy 2 8x you get 64x speed boost ie make 32x useless and obsolete like no point in it at all which makes 0 sence if this is true wouldnt it make more sence if it worked more along the idea of like if u got 2 8x it would be 16x speed boost making it so the 32 is not completely useless ie using the equation for it all being (2a)+(8b)+(32c)= overall speed boost where a b c is amount of them purchased
