The macro and micro do the exact same thing to the hammer spring just on a different level. Macro meaning bigger and micro mean smaller. Moving to 16 would be a bigger jump of tension on the hammer than moving the micro wheel. I believe the macro is 10 fps or so and the micro is about 2 fps or so depending on reg pressure. Also remember your valve knob for dwell timing. Closing it will slow your speed slightly and at times give you more consistency and better SD and spreads. Opening it for faster speeds and to have valve open longer but it can cause turbulence on your slug as it exits your barrel if open to long. But not always do better SD and spreads equal better accuracy, test at distance for slugs. Test at least 20 rounds for point of impact variation MOA average.
