Type the sentence end to end
Resist correcting mid-sentence. Finish the line, read the error report, then repeat the run.
Sentences bring back everything single-word drills leave out: capital letters, commas, full stops and the shift key. Typing complete sentences trains you to hold a steady rhythm through punctuation instead of stalling at every symbol, which is where most typing speed is actually lost. Every run reports words per minute, accuracy and the exact keys you missed.

Shift and punctuation break the rhythm you built on letters. That drop is normal and closes within a few sessions of sentence practice.
