Boy are you feeling lucky...
The busiest day to leave.
How do you feel about leaving at 2 am.
You might leave at 6 am and be there before noon. Or midnight. Or later. Depends on what happens.
Look at the traffic pattern/load from the Sunday Temple Burn through to noon on Monday.
There are so many things that can delay Exodus. Some you can watch for and leave earlier (forecast rain). Others can blindside you.
Whiteout and no one can move until the wind lets up. Rain on the playa and no one can move. Rain on the hill beside the playa can put water at the edge of the playa and no one can leave the playa. BRC is Closed: no one allowed out. The highway needs repair. The highway is washed out. There's a fire at or next to the highway. There's an accident, or two, or three. Stopping/gassing in Gerlach has congested traffic. Someone's inadequately secured load has spilled and needs to be cleared from the highway. Too much traffic (unsafe) on the highway - release of vehicles to the highway is slowed or stalled.
THEN, coming direct from the playa,
will they refuse to allow you to board: you're too dusty, clothes are too dusty or your carry-on is too dusty. Or they won't accept a dusty backpack.
You may be lucky, but the consensus is one needs to leave the day before to be "sure" (and that's not
sure, just significantly more likely) you are there in time for your flight. And if you get to BRC the day before, you have a chance to rest and get clean so you can board your flight.
A number of threads have addressed when to leave BRC to catch a flight.
Google eplaya to find those threads and hear some of the stories and advice.
Also google eplaya for the various ways to find a ride out of BRC to Reno.
Here's the three latest years of Exodus times.
2016 - when Exodus was closed from some hours while a missing minor was located.

2017 - fire beside road

2018 -

So it has been an hour to three to get out of BRC, plus up to nine to get to Wadsworth, plus time to Reno.
