Usually I am not measuring specific amounts of dry fuel to my water bottles to mix up, nor do I worry about cal/hour.
I carry the dry mix in an 8 to 12 oz dry bottle, and then get 3 or 4 water bottles out of that.
I also use Clip2 as a fuel, it works very well for me, 1 or 2 packs per water bottle.
I tried to use baggies, but very messy and the occasional rupture in a pack makes a big mess.
Usually I get an used juice bottle and recycle that, or a small liquid yogurt bottle for my dry mix, and then toss at an aid station.
When I make a dry supply bottle, I usually add Soy Protein as well, but no other additions.
From Hammer I use Perpeteum, SE, and HEED.
Then the straight malto-dextrin used for Home Brewing.
Have also used Dried Malt Extract (DME), and that has great flavor, but not as cost effective as Malto.
I almost never take a gel, but occasionally add them to my water bottle.
My system is far from scientific, and usually I am just winging it, based on how I feel.
There have been occasional bonks, but they are pretty rare.
I am also lucky in that I haven't had any Peterman/Losey style puke fests either.
One of my favorite fuels is Ramen, but mainly for longer events.
At OC100 I had Ramen and broth at the last 8 or 9 aid stations.
I think I could go for a long on time with a regular infusion of hot Ramen and Broth.
One of my favorite lines I share with Aid Station workers is that no matter now many Ultras I have been to, the best Ramen I have ever had is right then and there.
