Scaling Down

[JCasey1992]

I am brewing a british brown ale in a couple of days. Here is the recipe:

12.50 lb Pale Malt (2 Row) US (2.0 SRM)
2.00 lb Corn, Flaked (1.3 SRM)
1.00 lb Cara-Pils/Dextrine (2.0 SRM)
1.00 lb Caramel/Crystal Malt - 20L (20.0 SRM)
1.00 lb Caramel/Crystal Malt - 60L (60.0 SRM)
1.00 lb Caramel/Crystal Malt - 80L (80.0 SRM)
0.50 lb Chocolate Malt (350.0 SRM)
0.10 lb Roasted Barley (300.0 SRM)
1.00 oz Target [11.00%] (60 min)
0.50 oz Goldings, East Kent [5.00%] (15 min)
Whitbread Ale (Wyeast Labs #1099) with starter.

With that information, here is my question. The recipe above is for a ten gallon batch and I want to brew a 5.5 gallon batch. With that in mind, how would you scale this down? I used beersmith to do this but I'm not sure if I did it right. Here is the scaled down version:

6.00 lb 10.6 oz Pale Malt (2 Row) US (2.0 SRM)
1.00 lb 1.1 oz Corn, Flaked (1.3 SRM)
8.5 oz Cara-Pils/Dextrine (2.0 SRM)
9.9 oz Caramel/Crystal Malt - 20L (20.0 SRM)
9.9 oz Caramel/Crystal Malt - 60L (60.0 SRM)
9.9 oz Caramel/Crystal Malt - 80L (80.0 SRM)
4.9 oz Chocolate Malt (350.0 SRM)
1.0 oz Roasted Barley (300.0 SRM)
0.59 oz Target [11.00%] (60 min)
0.30 oz Goldings, East Kent [5.00%] (15 min)
Whitbread Ale (Wyeast Labs #1099) with starter.

Does this look right? If not, considering I've already milled the grain, is there any way to correct it? Thank you in advance for your help.

UPDATE: I found a good answer to my problem elsewhere. Therefore, there is no need to answer this post. Thank you all anyway.

I use brewgr for scaling recipes, it's so easy! Just enter in the recipe and pick initial size. After the recipe is saved just slide the scale recipe slider to where you want. Quicker and easier than reading these instructions.

I'll answer anyway as it might help someone else. Recipes scale directly. Half the volume of finished beer takes half the ingredients. The difference you might have is in the water used because one would normally boil off the same volume of water for a half size batch, not a percentage. If you normally boil off a gallon in a 10 gallon batch, you would still boil ff that same gallon in a 5 gallon batch or even in a 2 1/2 gallon batch.

One cannot expect software to scale a recipe unless one understands exactly how it works.
