Stitch Count Formula

I wanted to sum up my method of figuring how far I am on Peacock Feathers:

Amber's Formula for Finding Total Stitch Count "C" at Any WS Row after RS Row X on Peacock Feathers Shawl:

Last RS Row Number = X

X/2 = Y

Y(X) + Y = A (sts to middle of RS rows)

2A = B (for full RS width)

2B (to add WS rows) = C (Total Stitch Count Worked)

C/125,500 = % done
