Looking at it further, there's a quirk with the rounding off of the interest every 6 month period, where they round down one month and up on the other five.
It may have rounded down on the first month for whatever reason, rather than the second (as they did in the first six months).
Suppose it's possible it still comes out the same if they round it up the next five months.
