Most LD tournaments are "power matched" (also called "power paired" or just "powered"). In this system, after the first two rounds (often referred to as presets, as they are randomly paired beforehand), the pairings for the third round are decided on the basis that people with the same record (known as being in the same bracket) debate. For example, a 2‑0 would hit another 2‑0, a 1‑1 would hit another 1‑1, etc. Speaker points determine who hits who within each bracket (the 2‑0 with the highest speaks of any 2‑0 would hit the 2‑0 with the lowest speaks, second-highest hits second-lowest, etc.) After the third round, the debaters' cumulative records and speaks (rather than the results of their last round) place them in their brackets. Local tournaments sometimes use randomized brackets throughout their whole duration. Other tournaments use a "power protected" system during prelim rounds, in which a 3-0 would hit an 0-3 and a 2-1 would hit a 1-2. In "elimination rounds" after the primary four to six (or even eight) preliminary rounds, the top "seed" will "hit" the lowest "seed". Seeding is determined first by preliminary round records and then by the number of speaker points awarded by judges in preliminary rounds, with various tiebreakers (total number of opponent wins, speaker points after the highest and lowest given to each debater have been subtracted, judge variance, randomly assigned number, etc.) that follow should the statistics remain even.
