Say what you will about the Postal Service, being able to identify and key in an address every 2 seconds, even if it is only the zip code, and to keep doing this for a long period, is quite impressive. I'd be interested to know the female/male ratio of the workers who can handle a repetitive job like this.
I did over 10 years on a Letter Sorting Machine (LSM.) We were doing 60 per minute for 8 hours, minus two 15 minutes breaks.
The ratio was pretty much even between male and female. Usually the females maintained a lower error rate.
Edits were daily for every operator. Fall below 95% and you'd go back to training. Few ever had that happen. Personally I kept a 99.8% for 7 straight years, then slowly started dropping. We did have a couple sisters who kept a 100% rate forever.
