I was reading the FAQs for Zpoint calculation and I am having a hard time following the math on the Segment example. Perhaps a step has been omitted:


Every race your best segment times are recorded.
The fastest legitimate time of each segment is multiplied by 3 to get a "standard time".
The difference is then split into 600 possible points for the number of seconds below that you are.
Each day we calculate the average times for all riders over the last 90 days.

Example: Watopia Forward best time is 1:25 (85 seconds)
To get points you must be under 2:50 (170 seconds)
600 / 85 = 7.05 points per second you go under 2:50
Your 6 highest points are used, each capped to 100 points.

Shouldn't 1:25 be multiplied by 3, and thus the standard time be 4:15?
In the third sentence he states the difference is then split . . . . "Difference" is a term used in subtraction. I am not following this sentence. It looks as if the fastest time is simply divided into 600 to get a point per second value, 7.05s in the example cited. . Again, here is looks to me as if it should not be 7.05 points per second you go under 2:50, but under 4:15, which is the product of 3 x best time of 1:25.

Is it supposed to be that there is an extra step:

(Best Time)( 3) - Best Time = Standard Time? (1:25)(3) -1:25 = 2:50

thank you for taking a look at this. I am working so hard to sort this out.
