Double check my spoke lengths

So I was hit by a car last week and am now in a position to build a new front wheel since mine was ruined. It was a 36h rim laced to a 36h hub. Seeing as how I'm only 150lbs and don't thrash my bike around, I'd like to drop the spoke count.
I read here on Sheldon Browns site about lacing a 28h rim to a 36h hub (since my hub is fine I'll reuse it) and of all the places I looked it had the most understandable pattern. I haven't had a math class in quite a few years and am hoping somebody can double check my math. I used the formula Sheldon provided near the end of the article to calculate the spoke lengths.


I am open to suggestions on a working and symmetrical lacing pattern for a 24h front wheel, but there was a lot of difficult to understand information on that, something about no 24h pattern will put equal tensions on a 36h hubs flanges. I would think 20h would be pushing it, but again I'm open to suggestions if a good 20h pattern is around, and I think I could work the 28h design onto my rear wheel instead if the money I get is enough for the additional spokes.

I do not want people telling me about how stupid an idea this is, how it's bad to replace hubs into a different pattern than they have been laced, or about how leaving empty holes on the hub will create weak spots or spots of high tension on the flanges. I got all that and am doing it anyways. I just want some help/advice doing it.
