For those who wonder how I do my combos and plinks, here is how to perform the mp to lp plink.
Directions
---------------
Place your thumb in-between the two buttons 50-50, then shift to medium punch so that you have 90% of your thumb on medium punch and 10% on Light Punch,
Press medium punch then tilt your thumb to the left pushing down the light punch button. increase speed until you hit a sweet spot for the plink, then practice that till you develop muscle memory for it.
