I think it's cool that your getting into your turf so heavily. Most people just want to see green and it stop's there. You would make a good a horticulturist.

Your plan look's good, i see enough synthetic nitrogen that no matter what else you do you will have healthy grass, it's simple and that's a good sign. I wish i knew more about organic's so i could say whether or not the other product's were effective. The way you have two yard's side by side to experiment with is probably the best way to see what kind of result's you can get. Just remember that organic's are a long term proposition and that to get real result's is a long term (like a couple of year's) thing. Your also using zoysia, which in the summer will have hardly any weed pressure to begin with, i think that in the winter, when the grass is growing much more slowly, will give you a much better indication.

How your program handle's disease pressure is (i think) much more important. I have to question established zoysia in Austin needing 1"- 1-1/4" of water a week. I think you read something the wrong way. Using this -

i only come up with .53 of water a week, that's in Austin in full sun with no rain. .43 in. in partial shade with no rain. I think this is important because you don't want to overwater zoysia, it will weaken the turf, inviting disease and weed pressure.
