AMA Enduro Rules?

[SpeedyManiac]

Since I think I'm going to race a national enduro this year, I figured I better read up on the rules. So I did, and now I'm thoroughly confused. I thought they went to a similar style format to WEC/ISDE, but the website is very confusing.

Enduro format I'm used to:
We're given a time schedule with checkpoints and times, plus told the mileage inbetween. We're also told where there are special tests. So, a typical timesheet goes like this:

Get bike from impound - 9:00am
Start - 9:15am
T/C 1 - 9:47am/40km
T/C 2 - 10:30am/28km
T/C 3 - 11:50am/55km
etc
etc
Pre-finish - 3:40pm
Impound - 3:55pm

Throughout the course there would be usually 6 special tests. So during the day, you'd ride the trails at a quick but manageable pace to arrive at checkpoints hopefully 5-10 minutes early. You arrive early to grab gas, food, check the bike over, etc. Then roll through the time control on your minute and if the course organizers do things right, immediately go into a special test. The special test is where you actually race. Try to go as fast as possible. Your final score is all of the special test times plus any trail points from arriving early or late at a checkpoint. For time keeping, all that you need is a wrist watch. My route sheet is usually a piece of duct tape across the bar pad.

Is this in fact what the AMA National Enduro series is now? I see all this stuff about restarts, pauses and am a little confused.
