RIR Resource Allocation Data Inconsistencies

so, looking for somehting, i am wandering around potaroo etc, and i find these really strange reports about inconsistent data http://www.cidr-report.org/bogons/rir-data.html http://bgp.potaroo.net/stats/nro/ http://www.potaroo.net/drafts/draft-huston-ipv4-iana-registry-01.html and they seem to be current, in the sense they look to be generated daily (except the internet-draft, which i imagine is generated once a decade). are these, expecially one registry's data, as <ahem> unhappy as they seem? and how long has this been the case? randy
