Yeast pitch calculator, what gives?

Ok, It's my first time using one on Brewer's Friend and first time making a starter. I am trying to make my first lager (a 1.069 Maibock, 5 gal batch) and it says, I need 3 packs of liquid yeast in a 2L starter to create enough yeast cells. Can that be right? For 5 gal? Liquid yeast aint cheap. Can I get away with less?

Figure 1 pack in a 2 liter starter = 2 packs of yeast. 2 packs in a 4 liter starter = 4 packs of yeast. Yeast isn't cheap, that's correct, but neither is DME and your time.

So, should I add a 4L starter with 2 packs? That's a whole gallon in need to account for in my carboy. Like I said, first starter. Not trying to sound ignorant. My carboy is 6.5 gal, my batch size is actually 6 gal. It's getting kind of tight.
