After three days of "routine harvesting" on opening presents alone, I've found it reasonable to amass 100 canes in a 2 hour session if I'm not focused (during the harvesting, I'm chatting with folks, and answering frequent interruptions in RL). If I didn't chat, nailed a route where I was opening a present every 10-15 seconds, and left zones if the present drop rate wasn't being kind to me, I'd be a bit faster at it, but not at the rate of 100 canes per hour.
I don't know if that helps.
