Mt Whitney Zone Forums General Discussion question on walk in lotto process for overnight permits

Hi folks:

First post on this site for me! Is it accurate that in order to have a chance at unused permits for jm35 (overnight) the lotto takes place the *day of* the departure from the lone pine office?

I got day hikers passes on july 6th but realize we really need to break journey for a day at outpost camp/ trail camp to help with the climb. This is for july 5th. Looking for 2 wilderness permits and have been checking recreation.gov; is it possible to come on the 2nd or 3rd and still be eligible for lotto?
