Noob allgrain adaptation of Brandon O's graff for 1 gallon BIAB

[phug]

Can someone with some allgrain and extract experience take a look at this and tell me if I've gone way off the reservation? Many sets of eyes would be appreciated. for reasons of scale, and of package sizes available at my lhbs, allgrain with this size of grain bill seems to make the most sense without having ridiculous quantities of leftovers.

could someone take a look at this all grain adaptation based on making one gallon batches and limiting myself to what I can get, in the portions that make sense from my lhbs?

2 lbs 2 row malt
2 lbs Amber malt
.6 lbs Crystal 60 - 120 depending on the type of juice to be used.
1.2 oz Carapils
.6 oz hops of <6% AA or lower depending on preference (waiting to go to the LHBS to see what type I'd like, maybe mt. hood.

Mash grains for 1 hour at 155F in 1.5 gallons (5.67 litres) in grain bag
remove bag with grains, drain, and sparge with .56 gallons (2.11 litres) at 170F to replace water loss to grains.

Boil for thirty minutes with hop addition at the beginning of the boil.
Assume .3 gallons (1.13 litres) water loss to boil-off
Target volume is 1.2 gallons (4.54 litres)
Chill
Split into 750 portions, bottle any portions not being used immediately to keep as sterile wort for future batches.

Put one 750 ml portion in a one gallon container, top up with 3 litres apple juice, or apple cider. pitch notty, s-04, or s-05 and shake the heck out of it.

attach a blowoff tube. ferment at 60-65F until done, bulk prime with .75 oz table sugar or turbinado, or equivalent dextrose boiled in the least quantity of water I can. Or even 1.58 oz (~50ml) thawed apple juice concentrate to shoot for 2.5 volumes with the bottling temp at 60F

Bottle Condition.

This should give me enough wort to do 6 one gallon batches of graff using what I think might be a good all grain adaptation of Brandon O's recipe.

That being said, I've not brewed any beer, extract or otherwise, and have been cobbling this together from what I can figure out.

How far off did I stray in trying to scale this down and account for a stovetop biab recipe?

sorry for the horrible mishmash of Metric and US measurements.

Just confirmed that my pot can handle the boil volume, and that combined with my stove, I get a boiloff rate of 1.35 litres/.356 gallons per 30 minutes.

And Northern winter tap water is cold enough to cool that down pretty quickly without even having to add ice.

The only thing I didn't do was to check for heat loss over the course of an hour. I snuck in the boil while SWMBO was out of the house. I would have gotten strange looks for boiling an empty pot of water for 30 minutes with no intention of using it for any cooking purposes.
