Understanding the OID Code

Hi,
I've created a xls file with some codes (the number code and the pattern code)
I have gathered the number code by the test mode of the tiptoi (and learning chinese numbers 0-9) and the pattern code by taking photos and manual interpretation.
Found out that the pattern code is not that easy as some other documents make think. Also the checksum calculation by your oid-decoder doesn't work.
Maybe the codes can help to understand the real mechanism.
