Hindi speed plateau: chasing 30 wpm or fixing matra errors
Ritu is preparing for the UPMSP Hindi typing test, which requires 25 net wpm at 95% accuracy in a 10-minute passage. In her last three timed attempts on a 300-word passage she typed 258, 265 and 262 words gross, with 21, 17 and 19 errors respectively. Her net speed is therefore just under the cutoff. Error analysis shows 9 matra confusions (ि/ी, ु/ू), 4 punctuation omissions, 3 adjacent-key slips and 3 omitted words. She types the first two minutes at nearly 31 wpm, then slows and makes more errors; she never uses the final minute to proofread. Her coach suggests increasing speed to 30 wpm gross by doing 15-minute speed drills. Ritu has 12 days before the test and can practise 90 minutes daily. She wants to know whether to chase speed or accuracy, and how to allocate practice.
1. Calculate net speed and accuracy for each attempt. Is speed or accuracy the binding constraint?

Using the test's word-based penalty, net wpm = (gross words − errors) ÷ 10, and accuracy = (gross words − errors) ÷ gross words.
- 258 gross, 21 errors: net = 237 ÷ 10 = 23.7 wpm; accuracy = 237 ÷ 258 = 91.9%.
- 265 gross, 17 errors: net = 248 ÷ 10 = 24.8 wpm; accuracy = 248 ÷ 265 = 94.0%.
- 262 gross, 19 errors: net = 243 ÷ 10 = 24.3 wpm; accuracy = 243 ÷ 262 = 92.7%.
All three attempts fail both the 25 net wpm and 95% accuracy conditions. The important calculation is the error budget. At 95% accuracy, the gross speed needed for 25 net wpm is 25 ÷ 0.95 = 26.3 wpm, or about 263 words in 10 minutes. At 265 gross words, she may make at most 13 errors (265 × 0.05 = 13.25). Her best attempt had 17 errors, so she needs only 4 fewer errors, not a large speed increase. Accuracy is the binding constraint; a 30 wpm gross target would add pressure before her error rate is stable.
2. Design a 12-day practice plan that uses her 90 daily minutes and addresses the error clusters.

Days 1–6 should be accuracy-first, not speed-first. Suggested 90-minute block: 20 minutes of isolated matra drills, especially ि/ी and ु/ू in real words rather than single characters; 30 minutes of two 10-minute timed passages with a compulsory 2-minute proofread after each; 10 minutes of punctuation and spacing drills; 20 minutes updating an error log by category; 10 minutes reviewing the log and retyping only the incorrect words.
Days 7–12 should keep the same error work but add controlled speed. Use one passage at 24–25 wpm gross and one at 27 wpm gross, still with proofreading. The goal is not 30 wpm gross; it is 13 or fewer errors at 26–27 wpm gross. On days 11–12, simulate the full test: 10 minutes typing, 1 minute proofreading, no restarting. Track net wpm and errors per 100 words. Stop speed drills whenever the error rate rises above 5 per 100 words, because that is the pattern that is currently capping her net score.
