Ok, let's do the math:

Example:
Lean Body Mass = 200 lbs
Conver to Kilos 200lb/2.2 kg/lb = 90.9 kg

90.9 kg x 10 carb gr = 909 carb grams for 24 hours

Does that make sense so far ?

My guess is that you are using a Lean Body Mass that is not quite accurate. Your ideal weight is listed at 195, so your Lean Body Mass would be a number at best 5-7% below that number assuming you were a bodybuilder, completely buff.

Next, as you move from Friday to Saturday, switch your carb consumption from Hi GI carbs to Lower GI carbs. So some people here eat smarties and twizzlers on Friday which are candies made from Dextrose, then by Saturday afternoon to evening you should be looking for lower GI carbs, sweat potatoes, etc for your meals. Here's the link on GI index, the ideal is to fit more Lower GI carb in as you get closer to Saturday Evening. It's not a 50%/50% thing.
