According to AN730a of Microchip, and to modifications I had to make to the above algorithm work, augmentation (0-stuffing at the end of the calculation) should be the same length as the polynomial. As the polynomial here is 7 bits long, 7 zeroes should be shifted in.
Example CRC's can be found in the "Simplified Physical Layer Spec" for SD cards.

Thank you for your comment! You are correct, in that there should have been seven zeroes added as augmentation. The CRC calculation and diagram have been updated to show these missing zeroes and the new CRC result.
