Rating
Performance rating on puzzles carrying that theme: the average difficulty faced, plus a bonus for the score.
n
Attempts behind the figure. Themes with almost none are left out.
Bars
Start at 1000, not zero, so differences stand out.
Colour
Bars run from green at this solver's strongest reliable figure down through yellow to red 600 points below it, so the shade shows how far each one trails their best. Faint entries above that top out at green: a flawless run on a handful of puzzles is at least as strong, but by how much cannot be said. The scale is per solver and per tab.
Faint
Fewer than 25 attempts — treat with caution.

Difficulty Trend

Columns
Fixed rating bands, the same ranges the trainer offers. Share of each band, split into solved and missed. Numbers on the axis mark the band boundaries.
Time Spent
Weighted by time spent rather than puzzles solved. Thirty quick warm-ups outnumber three hard puzzles but take less of the clock, so this is the better measure of where effort went.
Figures
The four numbers above stay put whichever tab is chosen. TWPR and TOS are weighted by time: each puzzle's rating weighted by the time spent on it, and the share of time that went into puzzles that were solved. APR and SR are the per-puzzle equivalents, counting every attempt once. The pairs only diverge when a solver's time falls unevenly across difficulties.
Under
Performance rating for that band; italic when it rests on too few attempts.
Trend
Average rating attempted per week, against this solver's overall average of 1975.
