yes its true. i tried to use various cablenut configs and the speed varies. gourame's config may not work with your pc, but might work for others. my tip is, you can set the slider between 384 kbps up to 3000 kbps. when saving your config, rename it to settings 1, 2, 3 and so on. use each config setting, take note which one gave you the highest speed. but if you're curious enough to see what will happen, then slide it to more than 3thou.
