Playing for a certain number of hands

[revlis87]

If i am 4 tabling full ring 5-10 NL, how many hours would it take me to play 1,000 hands? I am trying to limit the amount I play, so I figure i am going to shoot for playing 1,000 hands a day if I am 4 tabling, but hopefully if I add 2-4 more tables of ring I can sacrifice a bit of bb/100 to play 2,000 hands a day. Whenever i reach the number of hands, I would quit for the day and do something else with my time. Obviously if the table is SUPER juicy i could stay but as a guideline. is this at all reasonable?
