How to read a Roll/JART Chart, and what’s really g

[QUOTE="Timr, post: 183424, member: 16236"] Jon, Here is the point that I was trying to make(and the point that you stated in your previous reply. I hope this example will better demonstrate my point). Let's say that you and I are riding on the same minute, and that we ride almost exactly the same speed. We enter into a test section that's 6 miles long run at 24 mph. Theres an emergency check at the front of the 6 mile test and a regular check at the end. You and I ride the exact thing time through the test. For this example, our time through the test is 5 minutes and 35 seconds. BTW, we're on row 20. So here's what happens. I enter the emergency check at :02 I get my score card marked: 20:02 then, on the end of the section I get a 25 (due to the time that I entered the first check, I arrive at the second check at 25:37). You zero the e-check with a perfect :30 So, your score card reads: 20:30 on the front end, but you get a 26 on the check out(your time at the second check is 26:05, you missed the flip of the cards by 5 seconds, your perfect score on the front end of the section cost you a whole minute on the back end, while my imperfect check cost me 28 tiebreaker points). My score is: 5/28 Your score is: 6/00 I win! :cool: and we both rode the 6 mile test in the EXACT same time. Yes, the start is a known control, so is the gas stop, but not gas availables. The finish can be a known control too, but only if it's labeled a known finish as it is in the roll chart that I posted. All Restarts and known controls too. Yes, and Yes! My enduro mentor is/was the king of riding possibles and not burning checks. He could read all of that stuff and ride fast at the same time. I find that the more time you spend studying before, the less I have to try and figure out during the race. I try and figure out where the tests will be and how long they will be. I then try and make notes on the roll chart, so I can read them at the resets and know what to expect. I know another very successfull A rider who marks places on the roll chart where he may want to gamble. He just writes the word Gamble followed by some ??? Then, when he reaches that point in the race, he decides what to do based on the how he feels, and what he thinks the club is trying to do. It's a total head game. One time, this gamble payed off huge for this rider that I'm refering to. I know because I was manning the check where he came in. It was at my club's race in '96. We had a SERA and SETRA sanction that day, and there were at least 17 AA riders at this race. They included Joey Hopkins, Alan Gravitt, and Terry Cunningham. Hopkins posted the fastest score through our check at just under 3 minutes, Cunningham had a 3 minute score, and the rider that I'm talking about zeroed the check. After the race, I asked him how he got through that tight section so quickly. He said that he had marked the spot as a place to gamble when he was studying the roll chart the night before. Then, he left the gas stop about 4 minutes hot and rode at a comfortable pace through that really tight section. The check that I was manning was really meant to be a going in check, but it was very hard to zero at 24 mph because of the 1.5 mile super tight section before it. This rider just rode to about .1 miles before our check and then pulled over where we couldn't see him and then waited for his minute to come up and the rolled in for his zero. Some people mark up their roll chart with lots of different color high lighters. They use some type of system like pink for speed changes/yellow for gas stops and so on. I don't do that. I just use a blue or black ball point pen to make notes in the margin. I can't imagine trying to ride the enduro with just computers and clocks and no roll chart. That's really flying blind. As we're trying to demonstrate here, the roll chart and it's information is there for you to exploit. Any rider that I see on the starting line who has a computer and no roll chart is a person that I have chance to beat even if that person is a faster rider than I am. (That doesn't mean that I do beat them, I just have a chance to because I kinda know what's going on and what to expect.) BTW, none of this applies to the upcoming SERA/SETRA enduro at Maplesville Alabama. It's a real butt kicker. The kind of event where I could leave my clock, computer, and roll chart holder in the truck and still get the same score. It' one of those put you head down and ride and hope you can make it to the end of the race kind of races. DAMN! I can't wait! [/QUOTE]
