I was shooting my MM VFT yesterday with a friend, and decided to decrease my DW. SOoo- I turned back the limb bolts 1.5 turns (each). I was shooting at a 30 yd target. I figured - less poundage = lower arrow velocity = more arrow drop - right? WRONG! My arrows now consistently grouped 6" higher than before. I checked the poundage, and it had decreased by about 4 lbs. What gives??
