Couple of things.

1. So what's your crank length? If your base measurement is from the center of the bottom bracket spindle, differences in crank length are being ignored.

2. How did you measure your leg length? Body parts are hard to measure with plus/minus just a few millimeters accuracy. The same thing can be said about the distance to the top of your saddle. Where, exactly, do you measure to?

3. What are you trying to accomplish? Are you trying to make some bike fitting formula maker happy or do you want to make yourself happy? The purpose of the formula is to short-cut the process of finding the saddle height that makes you happy. You should let it be your servant rather than make it your master.

If you want a nice analog saddle height system, try this: Go for a ride with someone whose judgement you trust. If your hips rock from side-to-side when you are pedaling, your saddle is too high. If your heels drop below your pedals at the bottom of the stroke, your saddle is too low.
