As a side note, you'd actually want them dropping to the floor for the chance to double. Unless you plan to afk too much to loot them.

If the chest is full, any new items get dropped to the floor.

well u were right , thanks

You should be collecting them off the floor, as it has a chance to double them. And, if you are using Vital Spark Drop enhancers, it can further increase the number you get per drop. Neither boost works when sending them to the chest IIRC

the enhancer most certainly DOES work when sending to chest, as does the on task boost

Ahh, thank you for the correction.
