Training stats explained
The trainer keeps a running scorecard for every algorithm you drill. The numbers are the point — they show which cases are fast, which are shaky, and where practice is paying off. Here’s what each one means and how it’s counted.
1. The numbers, per algorithm
Stats attach to each algorithm variant — the specific alg you drill, not just the case — so if you star a different variant it keeps its own history. For each you get your PB (best single), mean, ao5 (average of 5), your best ao5 ever, TPS (turns per second, emitted moves divided by seconds), and accuracy. Each rep’s time comes from the cube’s own move timestamps when every matched move carries one — the most accurate source — and falls back to your computer’s clock otherwise.
2. Accuracy is counted separately from time
Accuracy is a first-class stat, and it’s deliberately kept out of your time averages. A miss — a wrong turn during a rep — counts against accuracy but is never folded into your mean, ao5, or PB, so one fumble doesn’t poison your times. When you do turn the wrong way, cubrs shows you the undo path back to where you were and the rep resumes from the same step; that rep records one miss and no time. Practising a case with occasional slips lowers your accuracy without inflating your averages.
3. The 100-rep window vs your lifetime counts
Two things are tracked at once. Your lifetime counters are never trimmed — your rep total and records keep growing forever. Your averages, though, are computed over a rolling window of your newest 100 reps per variant (once your account is syncing), so the numbers reflect how you turn now, not how you turned months ago. Guests get a larger overall cap before old reps roll off.
4. Drill sets
You can drill a fixed set — 5, 10, or 25 reps, or just free reps — instead of an open-ended session. A set records a split for every rep and finishes with a summary showing the set’s mean, best, and accuracy, so you can compare one focused burst against another.
5. What records a time, and what syncs
Only real drill reps record times and feed these stats. The guided first solve and the notation lessons walk you through moves to teach them, so they deliberately don’t record times or count toward your averages. Everything that does count — your reps, records, and starred variants — is tied to your account and syncs across devices when you’re signed in.
