With B- Connectors they used to look for 600 pair in a 7 hour day and would allow a 3% failure rate (which I always felt was too high). My old partner and dear friend Morgan Harris used to do 1,000 pair in a 7 hour day with NO errors/failures, but he was a lunatic and at one time was the fastest splicer in the Bell System.

Lead sleeves took longer.

And absolutely - get comfortable.
