Totally depends on the recipe and mash schedule for me. I generally try to work it out with two equal batch sparges resulting in 7.5-8g in my keggle, clearly the size of the batches vary with the amount of grain used due to absorption. I've also started incorporating a mash-out infusion with the first batch on some recipes.
For a step and/or decoction mash everything goes out the window, but I frequently start at 1qt/lb and wind up around 2qts/lb. in those cases.
