Anyone familiar with this 3 gallon recipe?

I don't have the means to boil a full five gallons but I found this neat 3 gallon batch recipe.

The recipe increases the grain to make up for poor efficiency. But I think with a grain bag I could increase my efficiency (using Deathbrewers tips).

They don't mention what the gravity of any of their recipes are, that are listed on this page.

I was thinking about doing the Crystal Pale Ale fairly soon.

I'm thinking that this should work out well. BYO has a couple articles about brewing smaller batches and about skipping the sparge. But your grain amounts sound about right to make up for no sparge.

If you use Beersmith you can take any recipe and scale to any size you want.

I do only 3 gallon batches. I love the different beers I get to make and 3 gallons of one kind can sometimes be enough. Though I do have some I brew over and over. I am on a plan right now to make 52 different beers this year one beer a week. Some long term (Russian Imperial Stouts) and some short term for drinking now. This weeks it Yooper's IPA.
I use Beer Tools (Mac Fan) to cut recipes I think I might like down to 3 gallon size.
