That rule is really just saying "It's flexible so long as it's a quarter-inch thick or less." Of course, Dan's comments indicate you can easily have mail and scale that is thinner than this yet still rigid, so I'd further interpret that as "It can be flexible..."
Of course, 25% may be a bit too high. Notably, there isn't a single armor material that can be made into mail where 25% is actually less than the maximum DR (metals tend to hover around maximum DR of 20% DR/Inch). There are some options with scale, but with the possible exception of adamant those aren't that great of armor materials to start with.
