Beginner method vs CFOP on 2,000 shared random scrambles: average moves and turns per second needed for a 10 s solve

Goal

How many moves does a beginner layer-by-layer method need compared with CFOP on the same random scrambles, and what turns per second (TPS) does each need for a 10 second solve? Speed claims without move counts annoy me. The reader gets a table of mean, median and spread of move counts per method, measured on identical scrambles, plus the TPS that each mean implies at 10 s. It also gives a measured gap against the 20-move optimum, which I can check against Rokicki et al.

Plan

1. Write a pure Python 3.13 cube model (54 stickers, face turns, half-turn metric and quarter-turn metric). Test it: each move has order 4, R U R' U' repeated 6 times returns to solved, and 1,000 random 20-move scrambles keep a valid piece permutation and orientation parity.
2. Generate 2,000 random-state scrambles with a seeded generator that draws uniform permutations and orientations with the legal parity constraints. Do not use random-move scrambles. Save the seed and scrambles to the workspace.
3. Implement two solvers in code with no network. (a) Beginner layer-by-layer: cross, corners, middle edges, last layer, with the standard textbook algorithms. (b) CFOP-style: cross by short breadth-first search, F2L pairs by a depth-limited search per pair, OLL and PLL by lookup of the 57 and 21 cases generated from the group by search over a small algorithm list. If full OLL and PLL tables do not fit in time, say so, and use a documented optimal search for the last layer as a lower bound, labelled as such.
4. Verify every solution by applying it to its scramble and checking for the solved state. Count any failure and report it.
5. Report mean, median, 5th and 95th percentile moves per method and per stage, in half-turn metric. Compute TPS needed for 10 s and for 15 s per mean. Draw a bar chart and a histogram. Add a table of stage moves.
6. Success: both solvers pass 100% verification on 2,000 scrambles, and I report the means with a bootstrap 95% interval. Failure: if a solver fails on more than 1% of scrambles or cannot be finished, report that as a result and give the stage where it breaks. Compare the CFOP mean with the 50 to 60 move range from my 2026-10-05 post and say whether the data back it.
