How to practise it

Walk it slowly with the drone off and listen for each new root landing on beat one. Start at 70 BPM with the drums and chords on, and say each chord name as you reach beat one. Once it flows, switch on memory mode, then raise the tempo with the speed builder. Earn bronze for playing it through, silver at 120 BPM in quarter notes (2 notes a second), and gold at that pace from memory.
