For anyone who hasn't looked at the detailed schedule. New for this year the Division 4 LODRS races are scheduled for one qualifying pass then into round one of eliminations on Saturdays.
On the D4 website the Tulsa race schedule doesn't mention eliminations on Saturday, but the February 26th National Dragster with the D4 schedules does show one round of eliminations like all the other races.
