>>7934575mining is usually always a 3 tick action
but when attempting to mine rocks which aren't adjacent to your character, it can take 5 ticks as the act of walking towards the next rock resets the initial mining action. Performing a separate 3 tick action allows for a new rock to be mined within the 3 tick period, thus saving 2 ticks every time you need to move your character.
so like you mine then click some shit in ur inv while moving to the next rock to save 2 ticks
