Look at the timestamps you specified.

quote:
 good=1161088200
 bad=1161088500

1161088500 = 13 * 300 * 297715
1161088200 = 13 * 300 * 297714 + 3600

1161088500 =  3 * 300 * 1290098 + 300
1161088200 =  3 * 300 * 1290098

For timestamp 1161088500, 13*300 is a better choice, because it is exact match.
For timestamp 1161088200,  3*300 is a better choice, because it is exact match.
