Mt Whitney Zone Forums General Discussion Camp at Outpost; then Trail Camp? (need some advice)

I took 4 days in 2011.
Day 1 - Outpost Camp
Day 2 - Trail Camp
Day 3 - Summit & return to Trail Camp
Day 4 - Hike out

I did this for a few reasons. Get used to the altitude, slow pace to enjoy the journey, easier on the body. I was in no rush to get anywhere, other than be on the summit by noon.
