Just crushed the GOW BNE wood record. I chopped the whole map with 1 peon to ensure nothing was double chopped.

I don't know that anyone has ever noticed/pointed this out, but there are two different types of double chopping. One is where two peons chop the same piece of wood, and the peon who starts chopping second is wasting its time and wont receive any wood from that batch. The second type of double chop is when a peon takes in two "blocks" of wood instead of one, and in rare cases you have triple chops where they take three. By sticking to one peon you prevented the former from happening, but without microing to prevent the double/triple chops it wont effect your bottom line whatsoever.
So essentially, you chopped with 1 peon for no reason at all. But good job getting a new record. Like I said, the person who wants to sit around and micro each wood chop so that it only gets one block is going to get the max sooner or later.
