RC (Chronological Delay): Indicates how many draws ago a number (or combination of numbers) was last drawn. If a number has a chronological delay of 34, it means it has not appeared in the last 34 draws.

RL (Level Delay): In level synchronisms, it indicates for how many draws the group has retained its current composition. When one of the numbers in the group is drawn, it leaves the group: the remaining numbers continue together, the level decreases by one and the level delay restarts from zero. From that moment it increments at every draw, measuring for how many consecutive draws the formation resists without losing other components. A group with chronological delay 34 and level delay 22 consists of numbers absent for 34 draws that have shared the same formation for 22 draws. Previously the group was larger, then reduced by subsequent draws.
