Ok, so on my machine.. this number looks to be correct for exactly what it would seem to be:
mikembp:Volumes mike$ pmset -g log |grep -i "total sleep"
Total Sleep/Wakes since boot:35
mikembp:Volumes mike$ uptime
8:37 up 12 days, 1:13, 3 users, load averages: 1.65 2.21 2.39
mikembp:Volumes mike$
This is really about right, the last time I rebooted was the SMC firmware update.
Looking closer....
mikembp:Volumes mike$ pmset -g log |grep 'Sleep/Wakes'
