Though I have no idea what the hell that is or what you're on about, following the similar method, I get completely different answer to X1.

What board are you doing?

It's OCR.

I did a different board, but following your outlined method I get:

X1 = 3.627118644

X2 = 3.542454267

X3 = 3.53812734

X4 = 3.538116245

X5 = 3.538116245
