Each line is one lap measured against your fastest. Where a line steps up is exactly where that lap lost time; a gentle slope is being a little slower everywhere, a vertical jump is a feature or a bobble. Shaded bands are the features you have placed.
Pick a feature type, click Place a feature, then click where it starts on the course and where it ends. Put the entry a few metres before you brake for it and the exit where you are back up to speed, so the approach and the remount are inside the zone. Scroll to zoom in on the map and drag to pan, so an 8 m set of barriers is not a 3 px click. Features are saved with the race, and can be copied to another race on the same course.
Places you came nearly to a halt with no feature marked. If one of these is a feature you have not placed yet — a bog everybody runs, a tree root everybody clips — place it and it stops counting as a bobble.
Left on the table is the sum over laps of how much slower each pass was than your best pass — time you have already shown you can save. Cost per pass is how much longer a typical pass took than simply riding the same metres at your approach speed — the price of the feature itself, which only technique can cut.
One row per lap, one column per stretch of the course. A column that stays red top to bottom is somewhere you are slow every lap; a row that is red all the way across is a lap that went wrong. The bottom strip shows the median time and how many laps that sector was your worst.
Where every lap dips below the dotted running-pace line, you were off the bike. Where only one lap dips, something went wrong on that lap. Where the laps fan out, your line or your commitment varied.
One line per lap, drawn against distance into the lap, so the places where your heart peaks sit on top of the features that caused them. The heart trails the legs by 15 to 30 s: a peak lands after the run-up, in the sector where you have to ride it off.
In is the five seconds before the entry; peak is the highest reading between the entry and 40 s after the exit; settle is how long after the peak it took to get back within 2 bpm of the entry value. A rise that never settles is the bill for running the feature, and it is paid on the bike afterwards.
Tick races in the sidebar to include them. Every race is re-analysed with the current settings, so the comparison is like for like.
