You're looking at the wrong definition of "odd." I mean it to indicate numbers out of the ordinary. The vast majority of achievements give an amount of gamerscore divisible by 5 (and thus, it will end in either 0 or 5; e.g. 5, 10, 15, 20, 25, 30, etc.). In most games, ALL achievements are divisible by 5. And there are some achievements that are just 0, so while not divisible by 5, still follows the "ends in 0 or 5" rule.

Rarely, an achievement will end in an "odd" number, as far as achievements are concerned. This would be 1, 2, 3, 4, 6, 7, 8, or 9. And because every game that I know of has a total available gamerscore that is divisible by 5, these "odd" numbered achievements will have a "matching" achievement. If one is worth, say, 29, it is very likely that one will end in 1, to "even out" that "odd" gamerscore.

Some games, as evidenced by Winternova's list, have multiple "odd" GS achievements, that overall will even out to a number divisible by 5.

Fractions play no role in this. Gamerscore, the righteous, robust, and downright holy system it is, functions perfectly with only whole numbers. And, with the rare exception of games with sinful achievements that aren't divisible by 5, all ARE divisible by 5.
