Might not be far off if you don't have very effective tools (Peking Man had simple stone tools) or you've exhausted nearby suitable wood supplies like sticks you can just pick up or trees you can tackle, so you have to travel out and drag it back. The original study estimated 10 pounds (5kg) of wood foraged, trimmed and dried per hour of labour. That sounds low with a saw and an axe (and very low with a chainsaw), but might be about right with primitive tools including travel and processing and wood stack maintenance (no tarps either).
