Competition rules summary?

I've downloaded (and tried to read) the four sets of competition rules from SSA (National/Regional/FAI/Sport), but find myself falling asleep before reading them enough times to understand what they're trying to say.

Is there a terse, "simple English" version of the rules somewhere? ... a simple explanation of competition for rookie peelots? ... something that puts together tasks, turnpoints and minimum times without making assumptions of prior knowledge?

.... and a simple explanation of the difference between four said versions?

I like Bum Phillips' explanation of NFL football: "Two teams push against each other. Whoever pushes the hardest, wins."
