I essentially do the same, except maybe a little deeper with the mulch and I don't till it. I put about a foot of leaves on in the fall. Over the winter it compresses, composts, and provides worm and microbe food. By this time it is about 4-5" thick still with leaf, and about 1/2" of fresh, dark, perfect compost underneath. By fall the ground will still be covered, but it will be time for more. I start most of my seed indoors, except for beans/peas/beets/radishes/ etc. To plant just move the mulch, dig a hole big enough for the start, and put in the plant. Leave the mulch a little bit away from the stem, until the plant matures a bit.
EDIT: Maybe I should have put this in your gardening thread. Sorry, I got excited
I grow lots of comfrey for composting. Check out bocking #4 or bocking #14 comfrey plants. Very good for fertilizer/composting, but they are sterile, so they won't spread everywhere like regular comfrey.
I consider my gardening style to be a garden growing in about a 6" compost pile, with no-till.
For actual compost piles, I prefer wood dominant static piles. Hugelkultur type pile/beds.
