Interesting:
Found 3 notes where the date logic might be wrong. If it differs only for < 10 days, then just the EBTCheck data might be not accurate enough.

Actually, these were indeed found by me on November 13, 2010! So 27 November 2010 should at the very least be changed into 13 (and most probably I was not the first on EBT, so perhaps even an earlier date should be chosen)
