CPR timeline explained
Do you see the magic in the CPR timeline? Hopefully this article will help you see what we see. Note that the CPR timeline is a visualisation of a climbers performance over time. See the main Climber Performance Rating (CPR) article for an overview of CPR.
The lines show CPR curves, the colored candle sticks show the grade range difficulty of ascents climbed of a particular tick type during the time period and the bottom bar chart shows the number of ascents in that time period.
Note that colored candle sticks are overlayed on top of each other with the most pure ascent at the top (green, onsight), working down to failed attempts (grey) underneath.
The black curve is the main CPR curve for all ascents. It tracks your climbing performance overall, taking into account number of ascents, time decay and tick shift for different tick types (yes, an onsight is worth more than a red point). The other dotted CPR curves are for particular tick types, without tick shift.
The numbered dot is your rating at your most recent peak. If this peak was a while ago then a second current rating is also shown. Your rating is a measure of your climbing performance and is used for ranking. Each account has 6 ratings, a undecayed rating and decayed rating for each of trad, sport and boulder styles.

You should log all your ascents, even the failed attempts. The grey top candle stick, sitting above the black CPR curve is failed attempts or ascents of poor style. We have noticed that many climbers often have grey tops before jumping up a grade.
At the highest level of climbing, ascents are usually red points, so all our tick shifts are reference from the red point tick type (red bar). Some peoples CPR curves will closely match their red point curves, however other climbers may be relatively stronger at onsighting (green bar) and because of tick shifts, a hard onsight climb can push your cpr curve up to float above the red point curve.
A floating CPR means that a typical climber would be red pointing at a higher level then you are based on your onsight.
Then there are other climbers who red point far higher then their onsighting. jjobrien has now logged 336 attempts of a single climb - Evil Wears No Pants.
The menace of decay
It takes work to keep your CPR high. If you stop climbing your climbing performance will go down, so to will your CPR, which decays over time. CPR decays at a rate of about three quarters of a grade a year.
Your profile page shows your CPR Timeline since you started climbing. Sometimes you want to see more fine grained tick performance. Below each timeline in your profile page is some figure text with a link to your ascents logbook. Click on that link and which should take you to the ascents search page that was used to generate the timeline.
On the ascents page update the dates in the 'Climbed between' filter and click 'Apply filters'. Date format is yyyy-mm-dd, and partial dates like 2016 are acceptable.
