How simple is TOO simple?
I'm not overly concerned if NASA can do it. I have to be able to do it.
I use excel, values of 1,1,1.. or 1,2,1,2... whatever.
Then make a pie chart, remove the colors, print a few copies.
A thick layer of newspapers and the chart on the 'fridge, then a few of the real magnets, then I measure.
Fast, simple, reusable.
Short comings show quickly.
Like the dia is too big, 1000 turns won't fit...
I leave them there for a month or 3 with the others for comparisions.
And it's a handy place to stick keychains. Coupons. Mail. The neighbors cat.
YES! My wife hates it. A lot.
