Having this data is useful, but I can't help to think it would be more useful if it were compared with 27/8, or other networks. Is this slightly worse, or significantly worse than other networks?
I have only anecdotal information regarding 45/8.45/8 is assigned to Interop, and as such it is brought up-and-down as Interop's shows move in and out of convention centers. Starting at least 5 years ago, it has proved impractical to start announcing 45/8, since this causes immediate and massive amounts of traffic to flow into the show network.
The last time that I know that the full 45/8 was announced, traffic settled down to about a full T3's worth of bandwidth before the network engineers started announcing smaller /16 chunks as actually needed. Even /16 has proved impractical while the network is being built-out, before the show, because the build-out site typically has T1-ish bandwidth---again, saturated with a /16 being announced.
This information is very different from the RIPE Labs experiment which I think showed that certain "obvious" addresses (1.1.1.1 seemed to be the kicker in my short reading of their report) were being mis-used heavily. But I suspect that 27/8 would have similar issues to 45/8.
However, it is not clear to me that this is different from any other /8. In other words, for those that have a /8, they probably DO have to put up with a T3-worth of garbage flowing their way before they move the first useful packet. However, you don't get a /8 unless a T3 is small potatoes to you, hence...
