Thanks for the clarification. That's too bad really and I still don't understand the NBA lottery. They should have changed it back to a true lottery where the 13th best record can still land the top pick. Now that is a lottery! Also, I don't understand why if you finish with the 7th best record picks 4-6 are off the table. None of it makes sense to me.
The 13th pick CAN win the lottery ... they do a weighted drawing for all teams 1-14 (1st pick has like 25% chance at top pick, 14th is < 1 %). But, THEY ONLY DRAW THE TOP 3 SLOTS. Then, each team is slotted after that by reverse order of their record.
With the lottery reform scheduled for 2019 there are 2 changes slated.
1) Odds won't favor the top teams as much
2) They will draw the top 5 slots
Hope this helps. You can google it for more info.
