Set the macro at 1 and leave it there. Reg at 130. Set micro to 1.5. Load and shoot pellets, check speed. Increase micro 5 clicks at a time and recheck. Use finer increments to arrive at micro setting that shoots the pellets at the speed you want. At that point leave the micro where it is and note that Macro 1 will be the setting for your pellets. Then load the slugs and find their desired speed by increasing only the macro (which works by jogging the micro in a reversible manner by 5 clicks or so). Note the macro setting that works for your slugs and you’re done. You just switch between the two macro settings whenever you change ammo and leave the micro alone.
