multitabling question: 8 tabling sets, how many / hour

[DMACM]

I 8 table usually starting 4 than another 4 and so on. I assume that when people say they play continuously this is what they mean. I find it very hard to start instantly when one ends, although I am sure some people do it.

Lately I have been doing sets of 8 though and I find that much more enjoyable. Does anyone know how much less games you can get in an hour doing this? Assuming you can do 10-12 an hour using a continuous method, with sets would it be ~8 an hour?
