The general rule, for both v4 and v6, is that people should filter on whatever the minimum allocation/assignment size for each RIR block.

Did someone take the trouble to tell RIPE that?

193/8     /29
194/7     /29

That allows for 6291456 prefixes when fully deaggregated.

Someone recently posted a link (either on PPML or here -- I can't find it now) that showed ARIN's minima for the various v4 and v6 blocks.
