Seems like I recall reading somewhere that BS requires all the correct calculations and should only be used as a recipe book.
First thing that caught my eye was the beer color looked light for a Scotch Ale? BS shows 16.9 SRM.
Second the recipe I printed shows one pack of WLP028. Looking under the starter tab in BS it recommends 4pks?
First, I don't know in what context you heard that BS2 should only be used as a recipe book. It is actually pretty powerful modelling software once you set it up to mimic your process.
Next, beer color in the picture really means nothing. It is intended to give the user an approximation of how the beer will look, but the visual impact of beer color is highly dependent upon the path length that light needs to travel through the beer. Ignore the picture, look at the SRM, brew a beer and make any adjustments you feel necessary to the next time you brew it.
Lastly, it is typically stated by the White Labs that their packets are designed for pitching into 5 gallons of wort up to 1.060 gravity. I seldom find that it will be a proper pitch size for 1.040 gravity wort. Your OG is set for 1.079 -- almost twice the sugar content. So you are looking at two packages of yeast at a minimum. Then you factor in the age of the yeast and you could be looking for more.
Personally, I look at the BS2 starter page, but more often use the pitching rate calculator at
http://www.brewunited.com/yeast_calculator.php mostly because it allows the calculation for overbuilding of starters and multistep starters.
Also, if you are not doing yeast cell counts, your actual cell numbers are pretty variable as compared to the calculators. Luckily, I've found that there is enough forgiveness in yeast that close is good enough more often than not.
