About the XCJ10 and XCJ10 DTP

What are the XCJ10 and XCJ10 DTP?

The XCJ10 is simply your XC jumping clear rate from your last 10 XC runs (or fewer if you and your horse haven't reached 10 yet).  The XCJ10 DTP puts that clear rate into context by capturing how difficult the courses were.

In this 2-minute video, Sam explains the two Simple Metrics that will help you set cross country jumping benchmarks for you and your horse.

Note: The XCJ10 Adjustment that Sam explains is now named the XCJ10 Difference to Par to more clearly capture what it tells us. Same exact metric, just a new name.

How do I calculate the XCJ10?

The XCJ10 is the number of times your horse jumped clear cross country out of his last 10 XC starts, expressed as a percentage.

NOTES:
  • A clear round is any round you finished with 0 jumping penalties.  Do not count time penalties.
  • If you started the XC phase but didn't finish the course, that counts as an unclear round.
  • 10 previous runs is best, but you can use as few as 3.

How do I calculate the XCJ10 DTP?

The first step for calculating your XCJ10 Difference to Par (DTP) is determining each single DTP from each of your 10 most-recent XC starts. Then you just average the 10 to get your XCJ10 DTP. We show you below.

NOTES:
  • YOUR CLEAR RATE: 100% if you jumped clear, 0% if you had any jumping penalties or did not finish for any reason (for example, if you retired without jumping penalties, that would still be a 0% clear rate for that course).
  • When counting the # OF XC STARTERS WHO JUMPED CLEAR, only count XC starters who finished on 0 jumping penalties. Any starter who retired or was eliminated (even without jumping penalties) is a non-clear. 
  • The COURSE PAR is the # OF XC STARTERS WHO JUMPED CLEAR divided by the # OF XC STARTERS, expressed as a percentage (in other words, it's the course clear rate).
  • YOUR DIFF. TO PAR (DTP) is YOUR CLEAR RATE minus the COURSE PAR.  This is the number that tells us how much over or under par you were for the course.
  • Don't consider time penalties at all for these XCJ numbers.
  • Using 10 previous XC starts is best but you can use as few as 3.

In this example, an XCJ10 DTP of -8% means your XCJ clear rate is 8% lower than the average clear rate of the courses you contested. You'd prefer the XCJ10 DTP to be a positive percentage; the bigger, the better.
