Pitching Rate Question


Hello everyone, I have read the forum for quite some time, but this is my first post.
I will be making a Scotch Ale this weekend with an expected OG of 1.083. I just did the math for the starter and came up with about 295billion cells needed for the pitch. That's close to a gallon of starter for a 5 gallon batch, which just seems excessive to me. I normally brew in the 1.050 to 1.060 range, for which I like to use a one liter starter. If you all would be so kind as to check my math, I just can't imagine dumping a gallon starter in to a 5 gallon batch.
Thanks a bunch.
Denny
