I'm conducting a survey where I'm collecting information such as how long it took to prepare from about 20 of each track ( voice & security ) who passed recently. Now this will not have a precise result because I'm not taking into consideration previous experiences as I don't have access to all that data. But this will at least give us a hypothetical estimate of how long it could take to prepare and pass either ccie lab. I'll post my results.
