Why Practicing Near Your Target Tempo Backfires

The most common speed-practice mistake isn't practising too slow — it's parking the metronome just under your target and grinding. It feels productive because it's hard. But if your goal is 140 and your clean tempo is 115, every rep at 135 is a rep of tension, uneven timing, and near-misses. You're not practising the passage. You're practising playing it badly.

You get good at what you repeat

Repetition doesn't care whether the rep was good — whatever happens most often becomes the default. Reps near your ceiling come with stiff hands, clipped notes, and timing that lurches. Do fifty of those a day and stiff-and-lurching is what gets automated. This is why players who camp near their target for months are often stuck at the same real tempo the whole time.

The paradox: lower tempo, faster progress

Speed is relaxed, accurate movement gradually compressed in time. Reps at your clean tempo — where everything lands and nothing tightens — are the only reps that build that movement. So the tempo that looks like less ambition is actually the direct route: clean reps at 115, a 5 BPM bump, clean reps at 120. Climbing beats camping.

How close to target is too close?

• You can't play 4 clean, relaxed reps in a row at this tempo — too close. Back off.
• You feel your hands (or feet) brace before starting — too close.
• Clean but genuinely effortful — that's the working edge. Stay and bank reps.
• Occasional short bursts above clean tempo are fine as a test — just not as the diet.

Make the gap visible instead of frustrating

The reason players camp near the target is that the gap feels unbearable — 115 when you want 140 reads as failure. A progress chart reframes it: log the clean tempo each session and the gap becomes a line visibly closing, which makes it far easier to stay patient at the tempo that actually works.
