If one salad = one head of lettuce and each head take 60 days to mature than 60 plants are needed. If you want other stuff on your salad than you’ll need more.
I am pretty much done harvesting them now and between the two of them they produced about 1 salad a week for 10 continuous weeks. So for two adults, 2 plants x 2 adults x 7 days per week = 28 plants for 10 weeks of lettuce. Now then, it took about 10 weeks to get those two plants to the point of harvesting. So that would be another 28 plants to get ready to replace the others.
I thought about this as well. It does take about 8 weeks for 1 plant to be healthy enough for harvest. You would need a fairly large window or hydroponic setup to accommodate this. Assuming of course you harvested the entire plant. You could stagger the plants so that others are growing back while others are being harvested. You might be able to get away with half the plants.
My romaine takes about 2-3 weeks to grow back to where more can be harvested.
I’ll see if I can post a picture of what I am taking about
The above picture is one of my Aerogarden’s growing lettuce. The plant in the back is a week older then the smaller two. The seeds didn’t germinate so I had to replace them. After taking this picture, I trimmed back the large plant so the others could get more light.

Thanks Owen. Do you think leaf varieties rather than heads would yield more continuously?
I’ll give you some data on my bib lettuce http://our.windowfarms.org/2011/03/06/2-lettuces-in-1-pot-at-19-weeks/
